<P> The pylorus ( / paɪˈlɔərəs / or / pɪˈloʊrəs / ) , or pyloric part , connects the stomach to the duodenum . The pylorus is considered as having two parts , the pyloric antrum ( opening to the body of the stomach ) and the pyloric canal ( opening to the duodenum ) . The pyloric canal ends as the pyloric orifice , which marks the junction between the stomach and the duodenum . The orifice is surrounded by a sphincter , a band of muscle , called the pyloric sphincter . The word pylorus comes from Greek πυλωρός , via Latin . The word pylorus in Greek means `` gatekeeper '' , related to `` gate '' ( Greek : pyle ) and is thus linguistically related to the word `` pylon '' . </P>
