It is divided in two parts: * the [[pyloric antrum]], which connects to the body of the stomach. * the [[pyloric canal]], which connects to the duodenum. The pyloric [[sphincter]], or [[valve]], is a strong ring of smooth muscle at the end of the pyloric canal and lets food pass from the stomach to the duodenum. It receives [[sympathetic]] innervation from [[celiac ganglion]]. ==Medical significance== One medical condition associated with the pylorus is [[pyloric stenosis]]. In such conditions as [[stomach cancer]], when tumours may partly block the pyloric canal, a special tube can be implanted surgically to connect the stomach to the duodenum to assist food to pass from one to the other. This tube is called a '''pyloric stent'''. ==In popular culture== In [[John Kennedy Toole]]'s [[A Confederacy of Dunces]], the protagonist complains frequently about his "valve", which opens or shuts according to stress levels. ==Additional images== <gallery> Image:Gray1051.png|The longitudinal and circular muscular fibers of the stomach, viewed from above and in front.
