Churns food and begins protein digestion
Has two sphincters that control elimination of feces from the body
has regions called the cardia, fundus, body, and pylorus
Has recgions called the cecum, colon, rectum, and anal canal.
Receives secretions from salivary glands; mastication occurs here.

largest salivary glands whose ducts open by the upper second molars
stores and secrets bile into the duodenum
peritoneal membrane that attaches the stomach and duodenum to the liver
Salivary glands whose ducts open lateral to the lingual frenulum
Trace bile from its secretion to the gallbladder for storage and concentration, and then to the duodenum.
