Parts of Stomach

The stomach is divided into the following parts -

Fundus: This is dome-shaped and projects upward and to the left of the cardiac orifice. It is usually full of gas.

Body: This extends from the level of the cardiac orifice to the level of the incisura angularis, a constant notch in the lower part of the lesser curvature.

Pyloric antrum: This extends from the incisura angularis to the pylorus.

Pylorus: This is the most tubular part of the stomach. The thick muscular wall is called the pyloric sphincter, and the cavity of the pylorus is the pyloric canal.
