How We Digest Food 19

Food gives us energy. With this energy, we grow and move.

We can turn food into energy through digestion. First, teeth break

food down into small pieces. The pieces pass through a tube,

then reach the stomach. In the stomach, the food mixes with

stomach acid. It breaks down food for

easy digestion. Next, the food takes a

(Esophagus) from the food. At last, the waste

passes out of the body.
