The Sphincter of Oddi is the muscular valve that allows the flow of bile into the duodenum from the common bile duct when relaxed. The pyloric sphincter regulates the passage of food from the stomach to the small intestine, the ileocecal valve regulates the flow of material from the small intestine to the large intestine, and the ampulla of Vater is the opening where the common bile duct and pancreatic duct empty into the duodenum.
