Top 12 Amazing Facts About Internal Organs...
Though 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 stomach growl.
1. The 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.
2. The 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.
3. 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 razor blade 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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
the 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 detoxification.
9. The 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.
10. 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.
11. 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.
12. 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.
