Document Summary

Use saliva and teeth to chew cookie. Esophagus connects the mouth and the stomach used for swallowing. The stomach uses gastric juices to break down the cookie into liquid. Upper muscle relaxes to let food enter, then lower muscle mixes food with digestive juice. The small intestine furthers digestion and absorbs food. Undigested material from small intestine passes through large intestine. Liver produces bile (fluid), which is secreted into the duodenum. Secretes hormones insulin and glucagon into the blood. Rectum is the final section of large intestine, terminating at the anus. Small pores called gastric pits contain many exocrine cells that secrete digestive enzymes and hydrochloric acid into the lumen, or hollow region, of the stomach. Cholecystokinin is secreted by cells of the upper small intestine. Its secretion is stimulated by the introduction of hydrochloric acid, amino acids, or fatty acids into the stomach or duodenum.
