Human Body Facts

In my book called Readers Digest Pathfinders: The Human Body.  The following facts are:

1. Your body has a lifesaving trapdoor called the epiglottis.  It closes so no food can get out, otherwise it would be a trainwreck.
2. Most of your tastebuds are on your tongue, but you have them in your mouth and throat, too.  Each of your tastebuds detects one specific taste (sweet, sour, bitter, salty).
3. Girls become women and boys because of their sex hormones.  Girls become women around 10 or 11 and 12-14 for boys.  Girls develop breasts and broader hips and begin to menstruate and boys grow facial hair and their voices deepen.  In this cycle of life, both can produce children.
