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.
Mouth The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are mâ¦ore easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.
