What is gastric fundus?

The gastric fundus is the upper part of the stomach, situated above the body of the stomach and the entrance of the esophagus. It is typically dome-shaped and serves as a storage area for food and gases that are released during digestion. This region plays a role in the overall function of the stomach by helping to regulate the flow of contents into the main part of the stomach for further digestion. Additionally, it contains specialized cells that secrete gastric juices, contributing to the digestive process.
