cardiac sphincter
The pyloric sphincter muscle regulates the flow of chyme from the stomach to the duodenum just a few mL at a time.
The lower esophageal sphincter guards the entrance of the stomach from the esophagus.
The circular ring of muscle located at the entrance and exit of the stomach is referred to as a "sphincter" - the one at the entrance to the stomach is referred to as the cardiac sphincter, and the one at the exit of the stomach to the small intestines is referred to as the pyloric sphincter.
