Salivary amylase is an enzyme contained in saliva which assists in digesting the food. Once the food ha been chewed, it is swallowed & transported to the stomach through the esophagus with the assistnce of peristalsis. After the esophagus, the food reaches the gastro esophageal sphinter to ente the stomach. When in the stomach, gastric juices are produced which digests proteins & fats (Manore & Thompson, 2010).
