The digestive system also separates and disposes of waste products ingested and the food. Ingestion Food taken into the mouth is NuCulture first broken down into smaller pieces by the teeth. The tongue then rolls these pieces into balls called boluses. Together, the sensations of sight, taste, and smell of the food cause the salivary glands, located in the mouth, to produce saliva. An enzyme in the saliva called amylase begins the breakdown of carbohydrates (starch) into simple sugars. The bolus, which is now a battered, moistened, and partially digested ball of food, is swallowed, moving to the pharynx (throat) at the back of the mouth. In the pharynx, rings of muscles force the food into the esophagus, the first part of the upper digestive tube. The esophagus extends from the bottom part of the throat to the upper part of the stomach.
