Facts about Brain
human brain is the most complex and least understood part of the human
anatomy. There may be a lot we don't know, but here are a few interesting facts that we've got covered.
impulses to and from the brain travel as fast as 170 miles per hour.
Ever wonder how you can react so fast to things around you or why that
stubbed toe hurts right away? It's due to the super-speedy movement of
nerve impulses from your brain to the rest of your body and vice versa,
bringing reactions at the speed of a high powered luxury sports car.
brain operates on the same amount of power as 10-watt light bulb. The
cartoon image of a light bulb over your head when a great thought occurs
isn't too far off the mark. Your brain generates as much energy as a
small light bulb even when you're sleeping.
human brain cell can hold 5 times as much information as the
Encyclopedia Britannica. Or any other encyclopedia for that matter.
Scientists have yet to settle on a definitive amount, but the storage
capacity of the brain in electronic terms is thought to be between 3 or
even 1,000 terabytes. The National Archives of Britain, containing over
900 years of history, only takes up 70 terabytes, making your brain's
memory power pretty darn impressive.
brain uses 20% of the oxygen that enters your bloodstream. The brain
only makes up about 2% of our body mass, yet consumes more oxygen than
any other organ in the body, making it extremely susceptible to damage
related to oxygen deprivation. So breathe deep to keep your brain happy
and swimming in oxygenated cells.
brain is much more active at night than during the day. Logically, you
would think that all the moving around, complicated calculations and
tasks and general interaction we do on a daily basis during our working
hours would take a lot more brain power than, say, lying in bed. Turns
out, the opposite is true. When you turn off your brain turns on.
Scientists don't yet know why this is but you can thank the hard work of
your brain while you sleep for all those pleasant dreams.
say the higher your I.Q. the more you dream. While this may be true,
don't take it as a sign you're mentally lacking if you can't recall your
dreams. Most of us don't remember many of our dreams and the average
length of most dreams is only 2-3 secondsâ€“barely long enough to
continue to grow throughout human life. For years scientists and
doctors thought that brain and neural tissue couldn't grow or
regenerate. While it doesn't act in the same manner as tissues in many
other parts of the body, neurons can and do grow throughout your life,
adding a whole new dimension to the study of the brain and the illnesses
that affect it.
travels at different speeds within different types of neurons. Not all
neurons are the same. There are a few different types within the body
and transmission along these different kinds can be as slow as 0.5
meters/sec or as fast as 120 meters/sec.
brain itself cannot feel pain. While the brain might be the pain center
when you cut your finger or burn yourself, the brain itself does not
have pain receptors and cannot feel pain. That doesn't mean your head
can't hurt. The brain is surrounded by loads of tissues, nerves and
blood vessels that are plenty receptive to pain and can give you a
of the brain is water. Your brain isn't the firm, gray mass you've seen
on TV. Living brain tissue is a squishy, pink and jelly-like organ
thanks to the loads of blood and high water content of the tissue. So

Facts About Hair and Nails
they're not a living part of your body, most people spend a good amount
of time caring for their hair and nails. The next time you're heading
in for a haircut or manicure, think of these facts.
hair grows faster than any other hair on the body. If you've ever had a
covering of stubble on your face as you're clocking out at 5 o'clock
you're probably pretty familiar with this. In fact, if the average man
never shaved his beard it would grow to over 30 feet during his
lifetime, longer than a killer whale.
day the average person loses 60-100 strands of hair. Unless you're
already bald, chances are good that you're shedding pretty heavily on a
daily basis. Your hair loss will vary in accordance with the season,
pregnancy, illness, diet and age.
hair is about half the diameter of men's hair. While it might sound
strange, it shouldn't come as too much of a surprise that men's hair
should be coarser than that of women. Hair diameter also varies on
average between races, making hair plugs on some men look especially
human hair can support 3.5 ounces. That's about the weight of two full
size candy bars, and with hundreds of thousands of hairs on the human
head, makes the tale of Rapunzel much more plausible.
fastest growing nail is on the middle finger. And the nail on the
middle finger of your dominant hand will grow the fastest of all. Why is
not entirely known, but nail growth is related to the length of the
finger, with the longest fingers growing nails the fastest and shortest
are as many hairs per square inch on your body as a chimpanzee. Humans
are not quite the naked apes that we're made out to be. We have lots of
hair, but on most of us it's not obvious as a majority of the hairs are
too fine or light to be seen.
have more hair. They're said to have more fun, and they definitely have
more hair. Hair color determines how dense the hair on your head is.
The average human has 100,000 hair follicles, each of which is capable
of producing 20 individual hairs during a person's lifetime. Blondes
average 146,000 follicles while people with black hair tend to have
about 110,000 follicles. Those with brown hair fit the average with
100,000 follicles and redheads have the least dense hair, with about
grow nearly 4 times faster than toenails. If you notice that you're
trimming your fingernails much more frequently than your toenails you're
not just imagining it. The nails that get the most exposure and are
used most frequently grow the fastest. On average, nails on both the
toes and fingers grow about one-tenth of an inch each month.
lifespan of a human hair is 3 to 7 years on average. While you quite a
few hairs each day, your hairs actually have a pretty long life
providing they aren't subject to any trauma. Your hairs will likely get
to see several different haircuts, styles, and even possibly decades
before they fall out on their own.
must lose over 50% of your scalp hairs before it is apparent to anyone.
You lose hundreds of hairs a day but you'll have to lose a lot more
before you or anyone else will notice. Half of the hairs on your pretty
little head will have to disappear before your impending baldness will
become obvious to all those around you.
hair is virtually indestructible. Aside from it's flammability, human
hair decays at such a slow rate that it is practically
non-disintegrative. If you've ever wondered how your how clogs up your
pipes so quick consider this: hair cannot be destroyed by cold, change
of climate, water, or other natural forces and it is resistant to many
kinds of acids and corrosive chemicals.
Facts About Internal Organs
we may not give them much thought unless they're bothering us, our
internal organs are what allow us to go on eating, breathing and walking
around. Here are some things to consider the next time you hear your
largest internal organ is the small intestine. Despite being called the
smaller of the two intestines, your small intestine is actually four
times as long as the average adult is tall. If it weren't looped back
and forth upon itself it wouldn't fit inside the abdominal cavity.
Facts About Body Functions
may not always like to talk about them, but everyone has to deal with
bodily functions on a daily basis. These are a few facts about the
involuntary and sometimes unpleasant actions of our bodies.
regularly exceed 100 mph. There's a good reason why you can't keep your
eyes open when you sneezeâ€“that sneeze is rocketing out of your body
at close to 100 mph. This is, of course, a good reason to cover your
mouth when you sneeze.
clock in at about 60 mph. Viruses and colds get spread around the
office and the classroom quickly during cold and flu season. With 60 mph
coughs spraying germs far and wide, it's no wonder.
blink twice as many times as men do. That's a lot of blinking every
day. The average person, man or woman, blinks about 13 times a minute.
full bladder is roughly the size of a soft ball. No wonder you have to
run to bathroom when you feel the call of the wild. The average bladder
holds about 400-800 cc of fluid but most people will feel the urge to go
long before that at 250 to 300 cc.
75% of human waste is made of water. While we might typically think
that urine is the liquid part of human waste products, the truth is that
what we consider solid waste is actually mostly water as well. You
should be thankful that most waste is fairly water-filled, as drier
harder stools are what cause constipation and are much harder and
sometimes painful to pass.
have 500,000 sweat glands and can produce more than a pint of sweat a
day. With that kind of sweat-producing power it's no wonder that your
gym shoes have a stench that can peel paint. Additionally, men usually
have much more active sweat glands than women.
your lifetime, you will produce enough saliva to fill two swimming
pools. Saliva plays an important part in beginning the digestive process
and keeping the mouth lubricated, and your mouth produces quite a bit
of it on a daily basis.
average person expels flatulence 14 times each day. Even if you'd like
to think you're too dignified to pass gas, the reality is that almost
everyone will at least a few times a day. Digestion causes the body to
release gases which can be painful if trapped in the abdomen and not
production is necessary for good ear health. While many people find
earwax to be disgusting, it's actually a very important part of your
ear's defense system. It protects the delicate inner ear from bacteria,
fungus, dirt and even insects. It also cleans and lubricates the ear
Sex and Reproduction Facts
taboo as it may be in some places, sex is an important part of human
life as a facet of relationships and the means to reproduce. Here are a
few things you might not have known.
any given day, sexual intercourse takes place 120 million times on
earth. Humans are a quickly proliferating species, and with about 4% of
the world's population having sex on any given day, it's no wonder that
birth rates continue to increase in many places all over the world.
largest cell in the human body is the female egg and the smallest is
the male sperm. While you can't see skin cells or muscle cells, the ovum
is typically large enough to be seen with the naked eye with a diameter
of about a millimeter. The sperm cell, on the other hand, is tiny,
consisting of little more than nucleus.
three things pregnant women dream most of during their first trimester
are frogs, worms and potted plants. Pregnancy hormones can cause mood
swings, cravings and many other unexpected changes. Oddly enough,
hormones can often affect the types of dreams women have and their
vividness. The most common are these three types, but many women also
dream of water, giving birth or even have violent or sexually charged
teeth start growing 6 months before you are born. While few babies are
born with teeth in place, the teeth that will eventually push through
the gums of young children are formed long before the child even leaves
the womb. At 9 to 12 weeks the fetus starts to form the teeth buds that
will turn into baby teeth.
are always born with blue eyes. The color of your eyes depends on the
genes you get from your parents, but at birth most babies appear to have
blue eyes. The reason behind this is the pigment melanin. The melanin
in a newborn's eyes often needs time after birth to be fully deposited
or to be darkened by exposure to ultraviolet light, later revealing the
baby's true eye color.
are, pound for pound, stronger than an ox. While a baby certainly
couldn't pull a covered wagon at its present size, if the child were the
size of an oxen it just might very well be able to. Babies have
especially strong and powerful legs for such tiny creatures, so watch
out for those kicks.
out of every 2,000 newborn infants has a tooth when they are born.
Nursing mothers may cringe at this fact. Sometimes the tooth is a
regular baby tooth that has already erupted and sometimes it is an extra
tooth that will fall out before the other set of choppers comes in.
fetus acquires fingerprints at the age of three months. When only a
small fraction of the way through its development, a fetus will have
already developed one of the most unique human traits: fingerprints. At
only 6-13 weeks of development, the whorls of what will be fingerprints
have already developed. Oddly enough, those fingerprints will not change
throughout the person's life and will be one of the last things to
disappear after death.
human spent about half an hour as a single cell. All life has to begin
somewhere, and even the largest humans spent a short part of their lives
as a single celled organism when sperm and egg cells first combine.
Shortly afterward, the cells begin rapidly dividing and begin forming
the components of a tiny embryo.
Facts About Senses
The primary means by which we interact with the world around us is through our senses. Here are some interesting facts about these five sensory abilities.
eating too much, your hearing is less sharp. If you're heading to a
concert or a musical after a big meal you may be doing yourself a
disservice. Try eating a smaller meal if you need to keep your hearing
one third of the human race has 20-20 vision. Glasses and contact
wearers are hardly alone in a world where two thirds of the population
have less than perfect vision. The amount of people with perfect vision
decreases further as they age.
saliva cannot dissolve something, you cannot taste it. In order for
foods, or anything else, to have a taste, chemicals from the substance
must be dissolved by saliva. If you don't believe it, try drying off
your tongue before tasting something.
are born better smellers than men and remain better smellers over life.
Studies have shown that women are more able to correctly pinpoint just
what a smell is. Women were better able to identify citrus, vanilla,
cinnamon and coffee smells. While women are overall better smellers,
there is an unfortunate 2% of the population with no sense of smell at
nose can remember 50,000 different scents. While a bloodhound's nose
may be a million times more sensitive than a human's, that doesn't mean
that the human sense of smell is useless. Humans can identify a wide
variety of scents and many are strongly tied to memories.
small noises cause the pupils of the eyes to dilate. It is believed
that this is why surgeons, watchmakers and others who perform delicate
manual operations are so bothered by uninvited noise. The sound causes
their pupils to change focus and blur their vision, making it harder to
do their job well.
has a unique smell, except for identical twins. Newborns are able to
recognize the smell of their mothers and many of us can pinpoint the
smell of our significant others and those we are close to. Part of that
smell is determined by genetics, but it's also largely do to
environment, diet and personal hygiene products that create a unique
chemistry for each person.
Facts about Aging and Death
the very young to the very old, aging is a necessary and unavoidable
part of life. Learn about the process with these interesting, if
somewhat strange facts.
ashes of a cremated person average about 9 pounds. A big part of what
gives the human body weight is the water trapped in our cells. Once
cremated, that water and a majority of our tissues are destroyed,
leaving little behind.
and hair do not continue to grow after we die. They do appear longer
when we die, however, as the skin dehydrates and pulls back from the
nail beds and scalp.
the age of 60, most people will have lost about half their taste buds.
Perhaps you shouldn't trust your grandma's cooking as much as you do.
Older individuals tend to lose their ability to taste, and many find
that they need much more intense flavoring in order to be able to fully
appreciate a dish.
eyes are always the same size from birth but your nose and ears never
stop growing. When babies look up at you with those big eyes, they're
the same size that they'll be carrying around in their bodies for the
rest of their lives. Their ears and nose, however, will grow throughout
their lives and research has shown that growth peaks in seven year
60 years of age, 60-percent of men and 40-percent of women will snore.
If you've ever been kept awake by a snoring loved one you know the sound
can be deafening. Normal snores average around 60 decibels, the noise
level of normal speech, intense snores can reach more than 80 decibels,
the approximate level caused by a jackhammer breaking up concrete.
baby's head is one-quarter of it's total length, but by age 25 will
only be one-eighth of its total length. As it turns out, our adorably
oversized baby heads won't change size as drastically as the rest of our
body. The legs and torso will lengthen, but the head won't get much
Facts About Disease and Injury
of us will get injured or sick at some point in our lives. Here are
some facts on how the human body reacts to the stresses and dangers from
the outside world.
is the day of the week when the risk of heart attack is greatest. Yet
another reason to loathe Mondays! A ten year study in Scotland found
that 20% more people die of heart attacks on Mondays than any other day
of the week. Researchers theorize that it's a combination of too much
fun over the weekend with the stress of going back to work that causes
can make do longer without food than sleep. While you might feel better
prepared to stay up all night partying than to give up eating, that
feeling will be relatively short lived. Provided there is water, the
average human could survive a month to two months without food depending
on their body fat and other factors. Sleep deprived people, however,
start experiencing radical personality and psychological changes after
only a few sleepless days. The longest recorded time anyone has ever
gone without sleep is 11 days, at the end of which the experimenter was
awake, but stumbled over words, hallucinated and frequently forgot what
he was doing.
simple, moderately severe sunburn damages the blood vessels
extensively. How extensively? Studies have shown that it can take four
to fifteen months for them to return to their normal condition. Consider
that the next time you're feeling too lazy to apply sunscreen before
90% of diseases are caused or complicated by stress. That high stress
job you have could be doing more than just wearing you down each day. It
could also be increasing your chances of having a variety of serious
medical conditions like depression, high blood pressure and heart
human head remains conscious for about 15 to 20 seconds after it is
been decapitated. While it might be gross to think about, the blood in
the head may be enough to keep someone alive and conscious for a few
seconds after the head has been separated from the body, though reports
as to the accuracy of this are widely varying.
Facts About Muscles and Bones
and Bones provide the framework for our bodies and allow us to jump,
run or just lie on the couch. Here are a few facts to ponder the next
time you're lying around.
takes 17 muscles to smile and 43 to frown. Unless you're trying to give
your face a bit of a workout, smiling is a much easier option for most
of us. Anyone who's ever scowled, squinted or frowned for a long period
of time knows how it tires out the face which doesn't do a thing to
improve your mood.
are born with 300 bones, but by adulthood the number is reduced to 206.
The reason for this is that many of the bones of children are composed
of smaller component bones that are not yet fused like those in the
skull. This makes it easier for the baby to pass through the birth
canal. The bones harden and fuse as the children grow.
are about 1 cm taller in the morning than in the evening. The cartilage
between our bones gets compressed by standing, sitting and other daily
activities as the day goes on, making us just a little shorter at the
end of the day than at the beginning.
strongest muscle in the human body is the tongue. While you may not be
able to bench press much with your tongue, it is in fact the strongest
muscle in your body in proportion to its size. If you think about it,
every time you eat, swallow or talk you use your tongue, ensuring it
gets quite a workout throughout the day.
hardest bone in the human body is the jawbone. The next time someone
suggests you take it on the chin, you might be well advised to take
their advice as the jawbone is one of the most durable and hard to break
bones in the body.
use 200 muscles to take one step. Depending on how you divide up muscle
groups, just to take a single step you use somewhere in the
neighborhood of 200 muscles. That's a lot of work for the muscles
considering most of us take about 10,000 steps a day.
tooth is the only part of the human body that can't repair itself. If
you've ever chipped a tooth you know just how sadly true this one is.
The outer layer of the tooth is enamel which is not a living tissue.
Since it's not alive, it can't repair itself, leaving your dentist to do
the work instead.
takes twice as long to lose new muscle if you stop working out than it
did to gain it. Lazy people out there shouldn't use this as motivation
to not work out, however. It's relatively easy to build new muscle
tissue and get your muscles in shape, so if anything, this fact should
be motivation to get off the couch and get moving.
is stronger than some steel. This doesn't mean your bones can't break
of course, as they are much less dense than steel. Bone has been found
to have a tensile strength of 20,000 psi while steel is much higher at
70,000 psi. Steel is much heavier than bone, however, and pound for
pound bone is the stronger material.
feet account for one quarter of all the human body's bones. You may not
give your feet much thought but they are home to more bones than any
other part of your body. How many? Of the two hundred or so bones in the
body, the feet contain a whopping 52 of them.
Microscopic Level Body Facts
of what takes place in our bodies happens at a level that we simply
can't see with the naked eye. These facts will show you that sometimes
that might be for the best.
32 million bacteria call every inch of your skin home. Germaphobes
don't need to worry however, as a majority of these are entirely
harmless and some are even helpful in maintaining a healthy body.
shed and regrow outer skin cells about every 27 days. Skin protects
your delicate internal organs from the elements and as such, dries and
flakes off completely about once a month so that it can maintain its
strength. Chances are that last month's skin is still hanging around
your house in the form of the dust on your bookshelf or under the couch.
hundred million cells die in the human body every minute. While that
sounds like a lot, it's really just a small fraction of the cells that
are in the human body. Estimates have placed the total number of cells
in the body at 10-50 trillion so you can afford to lose a few hundred
million without a hitch.
shed about 600,000 particles of skin every hour. You may not think much
about losing skin if yours isn't dry or flaky or peeling from a
sunburn, but your skin is constantly renewing itself and shedding dead
day an adult body produces 300 billion new cells. Your body not only
needs energy to keep your organs up and running but also to constantly
repair and build new cells to form the building blocks of your body
tongue print is unique. If you're planning on committing a crime, don't
think you'll get away with leaving a tongue print behind. Each tongue
is different and yours could be unique enough to finger you as the
body has enough iron in it to make a nail 3 inches long. Anyone who has
ever tasted blood knows that it has a slightly metallic taste. This is
due to the high levels of iron in the blood. If you were to take all of
this iron out of the body, you'd have enough to make a small nail and
very severe anemia.
most common blood type in the world is Type O. Blood banks find it
valuable as it can be given to those with both type A and B blood. The
rarest blood type, A-H or Bombay blood due to the location of its
discovery, has been found in less than hundred people since it was
lips have a reddish color because of the great concentration of tiny
capillaries just below the skin. The blood in these capillaries is
normally highly oxygenated and therefore quite red. This explains why
the lips appear pale when a person is anemic or has lost a great deal of
blood. It also explains why the lips turn blue in very cold weather.
Cold causes the capillaries to constrict, and the blood loses oxygen and
changes to a darker color.
Here are a few things you might not have known about all different parts of your anatomy.
colder the room you sleep in, the better the chances are that you'll
have a bad dream. It isn't entirely clear to scientists why this is the
case, but if you are opposed to having nightmares you might want to keep
yourself a little toastier at night.
and mucus contain an enzyme (lysozyme) that breaks down the cell wall
of many bacteria. This is to your advantage, as the mucus that lines
your nose and throat, as well as the tears that wet your eyes are
helping to prevent bacteria from infecting those areas and making you
body gives off enough heat in 30 minutes to bring half a gallon of
water to a boil. If you've seen the Matrix you are aware of the energy
potentially generated by the human body. Our bodies expend a large
amount of calories keeping us at a steady 98.6 degrees, enough to boil
water or even cook pasta.
ears secrete more earwax when you are afraid than when you aren't. The
chemicals and hormones released when you are afraid could be having
unseen effects on your body in the form of earwax. Studies have
suggested that fear causes the ears to produce more of the sticky
substance, though the reasons are not yet clear.
is not possible to tickle yourself. Even the most ticklish among us do
not have the ability to tickle ourselves. The reason behind this is that
your brain predicts the tickle from information it already has, like
how your fingers are moving. Because it knows and can feel where the
tickle is coming from, your brain doesn't respond in the same way as it
would if someone else was doing the tickling.
width of your armspan stretched out is the length of your whole body.
While not exact down to the last millimeter, your armspan is a pretty
good estimator of your height.
are the only animals to produce emotional tears. In the animal world,
humans are the biggest crybabies, being the only animals who cry because
they've had a bad day, lost a loved one, or just don't feel good.
people live, on average, nine years longer than left-handed people do.
This doesn't have a genetic basis, but is largely due to the fact that a
majority of the machines and tools we use on a daily basis are designed
for those who are right handed, making them somewhat dangerous for
lefties to use and resulting in thousands of accidents and deaths each
burn fat more slowly than men, by a rate of about 50 calories a day.
Most men have a much easier time burning fat than women. Women, because
of their reproductive role, generally require a higher basic body fat
proportion than men, and as a result their bodies don't get rid of
excess fat at the same rate as men.
and primates are the only animals with unique fingerprints. Humans,
apes and koalas are unique in the animal kingdom due to the tiny prints
on the fingers of their hands. Studies on primates have suggested that
even cloned individuals have unique fingerprints.
indentation in the middle of the area between the nose and the upper
lip has a name. It is called the philtrum. Scientists have yet to figure
out what purpose this indentation serves, though the ancient Greeks
thought it to be one of the most erogenous places on the body.
human heart creates enough pressure to squirt blood 30 feet. No wonder
you can feel your heartbeat so easily. Pumping blood through your body
quickly and efficiently takes quite a bit of pressure resulting in the
strong contractions of the heart and the thick walls of the ventricles
which push blood to the body.The
acid in your stomach is strong enough to dissolve razorblades. While
you certainly shouldn't test the fortitude of your stomach by eating a
razorblade or any other metal object for that matter, the acids that
digest the food you eat aren't to be taken lightly. Hydrochloric acid,
the type found in your stomach, is not only good at dissolving the pizza
you had for dinner but can also eat through many types of metal.The
human body is estimated to have 60,000 miles of blood vessels. To put
that in perspective, the distance around the earth is about 25,000
miles, making the distance your blood vessels could travel if laid end
to end more than two times around the earth.You
get a new stomach lining every three to four days. The mucus-like cells
lining the walls of the stomach would soon dissolve due to the strong
digestive acids in your stomach if they weren't constantly replaced.
Those with ulcers know how painful it can be when stomach acid takes its
toll on the lining of your stomach.The
surface area of a human lung is equal to a tennis court. In order to
more efficiently oxygenate the blood, the lungs are filled with
thousands of branching bronchi and tiny, grape-like alveoli. These are
filled with microscopic capillaries which oxygen and carbon dioxide. The
large amount of surface area makes it easier for this exchange to take
place, and makes sure you stay properly oxygenated at all times.Women's
hearts beat faster than men's.The main reason for this is simply that
on average women tend to be smaller than men and have less mass to pump
blood to. But women's and men's hearts can actually act quite
differently, especially when experiencing trauma like a heart attack,
and many treatments that work for men must be adjusted or changed
entirely to work for women.Scientists
have counted over 500 different liver functions. You may not think much
about your liver except after a long night of drinking, but the liver
is one of the body's hardest working, largest and busiest organs. Some
of the functions your liver performs are: production of bile,
decomposition of red blood cells, plasma protein synthesis, and
aorta is nearly the diameter of a garden hose. The average adult heart
is about the size of two fists, making the size of the aorta quite
impressive. The artery needs to be so large as it is the main supplier
of rich, oxygenated blood to the rest of the body.Your
left lung is smaller than your right lung to make room for your heart.
For most people, if they were asked to draw a picture of what the lungs
look like they would draw both looking roughly the same size. While the
lungs are fairly similar in size, the human heart, though located fairly
centrally, is tilted slightly to the left making it take up more room
on that side of the body and crowding out that poor left lung.You
could remove a large part of your internal organs and survive. The
human body may appear fragile but it's possible to survive even with the
removal of the stomach, the spleen, 75 percent of the liver, 80 percent
of the intestines, one kidney, one lung, and virtually every organ from
the pelvic and groin area. You might not feel too great, but the
missing organs wouldn't kill you.The
adrenal glands change size throughout life. The adrenal glands, lying
right above the kidneys, are responsible for releasing stress hormones
like cortisol and adrenaline. In the seventh month of a fetus'
development, the glands are roughly the same size as the kidneys. At
birth, the glands have shrunk slightly and will continue to do so
throughout life. In fact, by the time a person reaches old age, the
glands are so small they can hardly be seen.
