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 digestion process begins in the mouth. Teeth, salivary glands, and the tongue work together to break down the food into a substance that can be easily swallowed. The teeth tear and smash the food. The salivary glands secrete enzymes, which prepare the food for digestion in the stomach.
