Breaking Down Digestion. The digestion process is a combination of chemical and mechanical digestion. Chemical digestion breaks down food via a chemical change, in which the digestive juices and enzymes break down food into components small enough to enter the GI tract, the blood cells or the lymph cells.
The mouth is the beginning of both mechanical and chemical digestion. Chewing breaks the food into smaller pieces and the saliva wets the food but also adds an enzyme call â¦ ed amylase that begins the digestion of carbohydrates.
