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.
Chemical digestion is the process through which the body of a mammal reduces food to a size where the nutrients that it contains can be absorbed into the bloodstream. The process begins in the mouth, continues in the stomach and ends when the digested particles move through the small intestine for absorption.hen the food reaches the stomach, different hormones trigger the body to begin releasing enzymes that further digest the food. Pepsin is the name of the enzyme that breaks down most of the proteins in the food. The digestion of carbohydrates, which began in the mouth with an enzyme called amylase, also continues here.
