The Digestive System and the Liver - The mouth: saliva, teeth, and tongue. By the time food leaves the mouth and is pushed down into the gullet (or esophagus), it has already received a sampling of all the kinds of punishment and prodding that will be provided by the 30-foot tube that lies ahead of it.
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.he first task of the digestive system is to break down food into a fine pulp (mechanical digestion). When the food is physical broken down, digestive chemicals break the food down into small molecules (chemical digestion). The mouth is the organ in which the process of digestion begins.
