Our Amazing Human Body

By Silver Dolphin Books on August 25, 2011

The human body is a marvelous and amazing machine.  When properly cared for, our bodies perfectly coordinate and orchestrate digestion, blood flow, breathing, sleeping, brain function, and countless other functions we rarely give much thought to.  Knowing how these important functions happen aids us in taking better care of ourselves and keeping us healthy.

Did you know? Fun facts about the body to share with your children:

  • Adults have 26 billion brain cells, 650 muscles, 206 bones, 100,000 miles of blood vessels, and many other parts that keep the body working.
  • Your body is 70 percent water.  It is found in your blood and in your cells.
  • The surface of your tongue is covered with about 10,000 taste buds.
  • The brain uses up a lot of energy.  It makes up only about 2 percent of your body weight, but uses up to 20 percent of the calories you eat!
  • Your skin is the largest organ in your body.
  • Your funny bone is not a bone at all.  It is the ulnar nerve.  This long nerve runs along the inside of your arm, through the elbow, then down to your hand.  At the elbow, it’s very close to the surface.  If you bump your elbow there, you get that pins-and-needles feeling in your forearm and hand.
  • The 29 bones of your skull form a strong shell around your brain, eyes, and inner ears.  Although your skull looks like one big bone, it is actually many pieces that grew together at places called sutures (SOO-churz).
