Stomachs are found in both vertebrates and invertebrates. The structure and size of the stomach vary within vertebrates. It can be a simple tube resembling other parts of the gastrointestinal tract, as found in some primitive vertebrates, while in other vertebrates it is a definite structure. In birds, the stomach is made up of a proventriculus and a gizzard, both which work together in digestion.
Structure of stomach:-
The stomach is a muscular organ that is found in our upper abdomen. If we were to locate it on our bodies, it can be found on our left side just below the ribs.
The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
The stomach, part of the gastrointestinal tract, is a digestive organ located between the oesophagus and the duodenum.
It has a ‘J’ shape, and features a lesser and greater curvature. The anterior and posterior surfaces are smoothly rounded with a peritoneal covering.
In this article, we shall look at the anatomy of the stomach – its position, structure and neurovascular supply.
