Lesson List


How the Digestive System Works

When you put a piece of food in your mouth the first thing you do is chew it.  Your teeth break the food into little pieces.  Your tongue moves the little pieces around.  A liquid called saliva makes the food wet.  Next you swallow.  The food goes down a tube into your stomach.

You can sometimes hear your stomach making noises.  These noises tell you that your stomach is working.  It is digesting your food.

When your food is digested, it is broken into very tiny pieces.  Some of this food goes into your blood.  This gives you energy.  Some of the food your body does not use.  This food leaves your body when you go to the bathroom.
