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 PATH OF DIGESTION. Mouth: Mechanical and chemical digestion begin in the mouth where food is chewed. The glands that act first are in the mouththe salivary glands. Saliva produced by these glands contains an enzyme called ptyalin that begins to digest the starch from food into smaller molecules (maltose).
