August 2017


Definition

The stomach is part of the digestive tract. It is a pouch located between the duodenum and the esophagus in the shape of a capital J. In the abdomen, it is located next to the epigastrium, a part of the abdomen located above the navel, and the left hypochondrium, to the left of the epigastrium. It is to the right of the liver, to the left of the spleen, in front of the pancreas, and above the intestines which follow it. It is composed of three segments: the fundus, at the top, the body in the middle, and the antrum, at the bottom. The adult stomach averages about 10 in long. The stomach pouch, in the body, is on average 6 in long, 3 in thick, and can contain between 1 and 2 liters. It is linked to the esophagus by the cardia, and to the duodenum by the pylorus.
