What Are 3 Functions Of The Stomach?

What are the parts of the stomach and their functions?

The stomach has four major regions: the cardia, fundus, body, and pylorus.

The addition of an inner oblique smooth muscle layer gives the muscularis the ability to vigorously churn and mix food.

The convex lateral surface of the stomach is called the greater curvature; the concave medial border is the lesser curvature..

What are 3 parts of the stomach?
