The pylorus is the region of the stomach that connects to the duodenum. It is divided into 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 which lets food pass from the stomach to the duodenum. It receives sympathetic innervation from the celiac ganglion. The adjectival form of pylorus is pyloric.
U.S. National Library of Medicine
The region of the STOMACH at the junction with the DUODENUM. It is marked by the thickening of circular muscle layers forming the pyloric sphincter to control the opening and closure of the lumen.
