The pyloric sphincter regulates the flow of substances leaving the stomach. Chyme moves in "spurts" through the sphincter into the small intestine. Large pieces of food are refluxed back into the body of the stomach, where they are reduced in size to about 2 mm so that they may pass through the sphincter.
