stomach

The stomach is a muscular organ in the abdomen that helps to digest food. It is located below the diaphragm and above the small intestine.

The stomach has three main parts: the fundus, the body, and the antrum. The fundus is the upper, rounded part of the stomach. The body is the middle part of the stomach. The antrum is the lower, narrower part of the stomach.

The stomach lining is made up of special cells that produce gastric juices. These juices contain acids and enzymes that help to break down food.

The stomach also has muscles that help to mix the food and juices together. This process is called churning.

After the food is churned, it is released into the small intestine.
