What You Never Knew About Your Body by Nobody: 9:20am On Feb 09, 2017 |
1. It’s possible for your body to survive without a
surprisingly large fraction of its internal organs.
Even if you lose your stomach, your spleen, 75%
of your liver, 80% of your intestines, one kidney,
one lung, and virtually every organ from your
pelvic and groin area, you wouldn’t be very
healthy, but you would live.
2. During your lifetime ,
you will produce enough
saliva to fill two
swimming pools.
Actually, Saliva is more
important than you
realize. If your saliva
cannot dissolve
something, you cannot taste it.
3. The largest cell in the human body is the female
egg and the smallest is the male sperm. The egg
is actually the only cell in the body that is visible
by the n*k*d eye.
4. The strongest muscle in the human body is the
tongue and the hardest bone is the jawbone.
5. The human feet have
52 bones, accounting for
one quarter of all the
human body’s bones.
6. Feet have 500,000 sweat
glands and can produce
more than a pint of
sweat a day.
7. The acid in your stomach is strong enough to
dissolve razorblades. The reason it doesn’t eat
away at your stomach is that the cells of your
stomach wall renew themselves so frequently
that you get a new stomach lining every three to
four days.
8. The human lungs
contain approximately
2,400 kilometres
(1,500 mi) of airways
and 300 to 500 million
hollow cavities, having a
total surface area of
about 70 square metres,
roughly the same area as one side of
a tennis court. Furthermore, if all of the
capillaries that surround the lung cavities were
unwound and laid end to end, they would extend
for about 992 kilometres. Also, your left lung is
smaller than your right lung to make room for
your heart.
9. Sneezes regularly exceed 100 mph, while
coughs clock in at about 60 mph.
10. Your body gives off
enough heat in 30
minutes to bring half a
gallon of water to a boil.
11. Your body has
enough iron in it to
make a nail 3 inches
long.
12. Earwax production is necessary for good ear
health. It protects the delicate inner ear from
bacteria, fungus, dirt and even insects. It also
cleans and lubricates the ear canal.
13. Everyone has a unique smell, except for
identical twins, who smell the same.
14. Your teeth start
growing 6 months before
you are born. This is
why one out of every
2,000 newborn infants
has a tooth when they
are born
15. A baby’s head is one-
quarter of it’s total length, but by the age of 25
will only be one-eighth of its total length. This is
because people’s heads grow at a much slower
rate than the rest of their bodies.
16. Babies are born with 300 bones, but by
adulthood the number is reduced to 206. Some of
the bones, like skull bones, get fused into each
other, bringing down the total number.
17. It is not possible to tickle yourself. This is
because when you attempt to tickle yourself you
are totally aware of the exact time and manner
in which the tickling will occur, unlike when
someone else tickles you.
18. Less than one third
of the human race has
20-20 vision. This means
that two out of three
people cannot see
perfectly.
19. Your nose can remember 50,000 different
scents. But if you are a woman, you are a better
smeller than men, and will remain a better
smeller throughout your life.
20. The human body is estimated to have 60,000
miles of blood vessels.
21. The three things
pregnant women dream
most of during their first
trimester are frogs,
worms and potted
plants. Scientists have no
idea why this is so, but
attribute it to the
growing imbalance of hormones in the body
during pregnancy.
22. The lifespan of a human hair is 3 to 7 years
on average. Every day the average person loses
60-100 strands of hair. But don’t worry, you
must lose over 50% of your scalp hairs before it
is apparent to anyone.
23. The human brain cell can hold 5 times as
much information as an encyclopedia.Your brain
uses 20% of the oxygen that enters your
bloodstream, and is itself made up of 80% water.
Though it interprets pain signals from the rest of
the body, the brain itself cannot
feel pain.
24. The tooth is the only part of the human body
that can’t repair itself.
25. Your eyes are always the same size from
birth but your nose and ears never stop growing.
26. By 60 years of age, 60% of men and 40% of
women will snore.
27. We are about 1 cm taller in the morning than
in the evening, because during normal activities
during the day, the cartilage in our knees and
other areas slowly compress.
28. The brain operates
on the same amount of
power as 10-watt light
bulb, even while you are
sleeping. In fact, the
brain is much more
active at night than
during the day.
29. Nerve impulses to and from the brain travel
as fast as 170 miles per hour. Neurons continue
to grow throughout human life. Information
travels at different speeds within different types
of neurons.
30. It is a fact that people who dream more often
and more vividly, on an average have a higher
Intelligence Quotient.
31. The fastest growing nail is on the middle
finger.
32. Facial hair grows faster than any other hair
on the body. This is true for men as well as
women.
33. There are as many
hairs per square inch on
your body as a
chimpanzee.
34. A human foetus
acquires fingerprints at
the age of three months.
35. By the age of 60, most people will have lost
about half their taste buds.
36. About 32 million bacteria call every inch of
your skin home. But don’t worry, a majority of
these are harmless or even helpful bacteria.
37. The colder the room you sleep in, the higher
the chances are that you’ll have a bad dream.
38. Human lips have a
reddish color because of
the great concentration
of tiny capillaries just
below the skin.
39. Three hundred
million cells die in the
human body every
minute.
40. Like fingerprints, every individual has an
unique tongue print that can be used for
identification.
41. A human head remains conscious for about
15 to 20 seconds after it is been decapitated.
42. It takes 17 muscles to smile and 43 to frown.
43. Humans can make do
longer without food than
sleep. 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.
44. The most common blood type in the world is
Type O.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 discovered
45. Every human spent
about half an hour after
being conceived, as a
single cell. Shortly
afterward, the cells
begin rapidly dividing
and begin forming the
components of a tiny
embryo.
46. Right-handed people live, on average, nine
years longer than left-handed people do. This 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 year.
47. Your ears secrete
more earwax when you
are afraid than when
you aren’t.
48. Koalas and primates
are the only animals
with unique fingerprints.
49. Humans are the only animals to produce
emotional tears.
50. The human heart creates enough pressure to
squirt blood 30 feet in the air. 1 Like |
