The human stomach is subdivided into four regions: the fundus, an expanded area curving up above the cardiac opening (the opening from the stomach into the esophagus); the body, or intermediate region, the central and largest portion; the antrum, the lowermost, somewhat funnel-shaped portion of the stomach; and the pylorus, a narrowing where the. The stomach is lined by a mucous membrane that contains glands (with chief cells) that secrete gastric juices. Two smooth muscle valves, or sphincters, keep the contents of the stomach contained: the cardiac or esophageal sphincter and the pyloric sphincter. The arteries supplying the stomach are the left gastric, the right gastric, and the.

The stomach wall: A micrograph that shows a cross section of the stomach wall, in the body portion of the stomach. This consists of an epithelium, the lamina propria underneath, and a thin bit of smooth muscle called the muscularis mucosae. The submucosa lies under this and consists of fibrous connective tissue that separate the mucosa from the. Digestion The stomach, gallbladder, and pancreas work together as a team to perform the majority of the digestion of food. Food entering the stomach from the esophagus has been minimally processed — it has been physically digested by chewing and moistened by saliva, but is chemically almost identical to unchewed food.
