DISCOVERY: Unusual Facts About The Human Body [Contd].

6: Long Intestines

­ The small intestine is about four times as long as the average adult is tall. If it weren't looped back and forth upon itself, its length of 18 to 23 feet wouldn't fit into the abdominal cavity, making things rather messy.

7: Bacteria

This will really make your skin crawl: Every square inc­h of skin on the human body has about 32 million bacteria on it, but fortunately, the vast majority of them are harmless.

8: Source of Body Odor

Th­e source of smelly feet, like smelly armpits, is ­sweat. And people sweat buckets from their feet. A pair of feet have 500,000 sweat glands and can produce more than a pint of sweat a day.

9: Sneeze Speed

­The air from a human sneeze can travel at speeds of 100 miles per hour or more -- another good reason to cover your nose and mouth when you sneeze -- or duck when you hear one coming your way.

10: Blood Distance

­ Blood has a long road to travel: Laid end to end, there are about 60,000 miles of blood vessels in the human body. And the hard-working heart pumps about 2,000 gallons of blood through those vessels every day.
