  • The human hand has 27 bones; your face has 14!

  • The longest bone in your body? Your thigh bone, the femur -- it's about 1/4 of your height. The smallest is the stirrup bone in the ear which can measure 1/10 of an inch.

  • You have over 230 moveable and semi-moveable joints in your body

  • You have over 30 facial muscles which create looks like surprise, happiness, sadness, and frowning.

  • Eye muscles are the busiest muscles in the body. Scientists estimate they may move more than 100,000 times a day!

  • The largest muscle in the body is the gluteus maximus muscle in the buttocks.

  • HOW LONG ARE YOUR INTESTINES? At least 25 feet in an adult. Be glad you're not a full-grown horse -- their coiled-up intestines are 89 feet long!

  • Chewing food takes from 5-30 seconds

  • Swallowing takes about 10 seconds

  • Food sloshing in the stomach can last 3-4 hours

  • It takes 3 hours for food to move through the intestine

  • The body of an adult contains over 60,000 miles of blood vessels!

  • An adult's heart pumps nearly 4000 gallons of blood each day!

  • Your heart beats some 30 million times a year!

  • The average three-year-old has two pints of blood in their body; the average adult at least five times more!

  • A "heartbeat" is really the sound of the valves in the heart closing as they push blood through its chambers.

  • As an adult, you may have more than 20 square feet of skin -- about the size of a blanket.

  • You are likely to shed some 40 pounds of skin in a lifetime.

  • Right now there are over a million dust mites, microscopic critters invisible to the naked eye, on your mattress and pillow, chomping on the dead skin cells that fell off you last night!
