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 teeth chop the food up into smaller pieces which then pass through the digestive system. Chemical digestion is the breaking down of food particles through chemical reactions. Chemical and mechanical digestion combine to process food, absorbing nutrients and minerals and discarding the waste.Very little mechanical digestion occurs outside of the mouth.hemical digestion is the breaking down of food particles through chemical reactions.
