Human Mysteries - part 1

The Human Body is a treasure trove of mysteries, one that still confound doctors and scientists about the details of its working. It's not an overstatement to say that every part of your body is a miracle. Here are fifty facts about your body, some of which will leave you stunned. I will share all 50 facts over the next few days.

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 naked eye.

4. The strongest muscle in the human body is the tongue and the hardest bone is the jawbone.

5. 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 razor blades. 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 1,500 miles of airways and 300 to 500 million hollow cavities, having a total surface area of about 70 square meters, roughly the same area as one side of a tennis court. 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.
