Weird Human Body Facts

The human body is an extremely complex and intricate system, some weird facts about human body.
31.
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.

32.
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.

33.
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.

34.
Sneezes regularly exceed 100 mph. There's a good reason why you can't keep your eyes open when you sneeze–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.

35.
Coughs 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.

36.
Women 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.

37.
A 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 400800 cc of fluid but most people will feel the urge to go long before that at 250 to 300 cc.

38.
Approximately 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 waterfilled, as drier harder stools are what cause constipation and are much harder and sometimes painful to pass.

39.
Feet have 500,000 sweat glands and can produce more than a pint of sweat a day. With that kind of sweatproducing 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.

40.
During 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.
