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. The mouth begins the digestive process when food enters and chewing begins. The mouth creates saliva, which helps break down the food and sends it along the rest of the digestive tract. Alcohol is second only to tobacco in itâs ability to increase the risk of mouth cancer and gum disease.
