The saliva allows a boulous of food to be formed so that it is easier deglutition. Salivary glads also contain sodium bicarbonate which acts as a buffer which alliviates some o the acid within the stomach. Salivary amylase is an enzyme used to digest starch.  <br \/>\nThe esophagus is a muscular tube with circular and longitudinal smooth muscles which contract and push the food through. The muscular contractions are also know as peristalsis they are involuntary contractions. <br \/>\nThe stomach is the first part of the gastrointestinal tract and uses two types of digestion chemical and physical. Chemical digestion is done through enzymes and Hydrochloric acid. Physical digestion is done by mixing and churning of the food.  Pepsinogen is an inactive enzyme secreted by peptic cells however, when it comes into contact with hydrochloric acid and protein it becomes active and aids in digestion. Chief cells secrete hydrochloric acid which is used in the Fundic region.  The pyloric sphincter then meets up to the duodenum which is the start of the small intestine.","replyPages":[{"page":0,"digests":[],"more":0}]}],"more":false},"comments":[]},"http":{"code":200,"status":"OK"},"redirectUrl":null,"javascript":null,"notices":{"warning":[],"error":[],"info":[],"success":[]}}
