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 is the organ in which the process of digestion begins. It starts the process of mechanical digestion by grinding the food with teeth. Also in the mouth, an enzyme called salivary amylase begins to break down long starch molecules into maltose. Once the food is ready to be swallowed it is gathered into a ball called a bolus and sends to the part of the bolus called the pharynx.
