Digestion is both a mechanical and chemical process. For example, the teeth in the mouth help to physically crush and break-up the food into smaller pieces to increase their surface area so that it can be processed chemically in later stages of digestion. The Stomach secrets acids and enzymes which chemically break down the food into very small particles and molecules, so that these can be processed in later stages of digestion.
