Answer 1

Digestion occurs in three main ways: We chew our food, and our teeth break down the food into smaller pieces. Also, the liquid in our mouths (saliva) causes a chemical reaction that starts to digest the food. In our stomach, chemicals called “enzymes” change the food into smaller molecules that the body can use.
