Stomach At Biology Glossary

What is it? The part of the vertebrate gut system that follows the esophagus. It is expanded to form a chamber, and its walls secrete pepsinogen, giving rise to pepsin, rennin, and hydrochloric acid. Gastric secretions also include mucin, which lubricates the food mass that is passed a little at a time to the small intestine via the pyloric sphincter.
