In the case of humans, the stomach is found in the abdominal cavity and is one of the largest organs, and can even become larger since its tissue is elastic unlike other organs. The stomach has an irregular shape, similar to that of a pouch and is located between the esophagus and the small intestine.

The apparatus The digestive system has many organs, all of them fulfilling equally important functions since in the absence or complications of one of them the individual immediately presents discomfort. The stomach is, however, the main element of the entire complex digestive system since it is there where the processes of digestion. The stomach is divided into several parts according to the type of function performed in each one: the first and immediately following the esophagus is the cardia, then the fudus, the central body, the antrum, the pylorus, and the

duodenum which is the final section that connects to the small intestine.

Thus, the stomach leaves the food material ready so that it circulates without great difficulty through the intestine or is later discarded.
