It is a ring of smooth muscle located at the pylorus which regulates the passage of food and gastric juices from the stomach into the duodenum. The ileocecal valve is located between the small and large intestine, the diaphragmatic valve does not exist, and the esophageal sphincter controls the release of food from the esophagus into the stomach.
