Pyloric Sphincter

The pyloric sphincter is at the end of the pyloric canal, where the circular layer of fibers in the muscular pyloric canal walls thicken to form this powerful muscle. The pyloric sphincter muscle serves as a valve that prevents regurgitation of food from the intestine back into the stomach.
