Digestion is the process of breaking down food into simpler substances. Digestion is of two types: mechanical or physical digestion, and chemical digestion.

Mechanical Digestion (ex. chewing your food) and Chemical Digestion (ex. your spit breaking down the food). Those examples happen in the mouth, but both types happen elsewhere in the body, too.

Mechanical and chemical digestion. In mechanical digestion the teeth breakdown food into smaller pieces and in chemical digestion the salivary glands breaks down the food molecules.
Enzymes are involved in the digestion of all types of foods except, of course, the foods that cannot be digested (like cellulose).
There are two kinds of digestion: mechanical and chemical.
