Stomach

STOMACH

The stomach is a J shaped organ near the top of the abdomen.

Food begins its journey to the stomach soon after a person swallows. The food moves down from the throat and into the esophagus. The stomach is located at the end of the esophagus.

The muscles of the stomach help it break down and digest food. Within its lumen lining, certain regions of the stomach also produce enzymes that help digest food. The enzyme pepsin, for example, breaks down proteins so that they can become amino acids.

The stomach also helps store chyme until it moves to the intestines. Chyme refers to food that has mixed with stomach secretions.

Anatomists usually divide the stomach into five subparts. These are:

  • The cardia: Located just beneath the esophagus, this portion of the stomach includes the cardiac sphincter. The sphincter prevents food from flowing back up the esophagus or into the mouth.
  • The fundus: This is situated to the left of the cardia and underneath the diaphragm.
  • The body: Food begins breaking down in the body, which is also the largest part of the stomach.
  • The antrum: This is the lower part of the stomach. It contains partially digested food before it flows to the small intestine.
  • The pylorus: This portion of the stomach connects to the small intestine. It includes a muscle called the pyloric sphincter, which controls when and how much stomach content flows into the small intestine.
