pylorus
The distal aperture of the stomach or abomasum, opening into the duodenum. The term pylorus is variously used to mean the pyloric part of the stomach, and the pyloric antrum, canal, opening or sphincter. A ring of muscles, the pyloric sphincter, serves as a ‘gate’, closing the opening from the stomach to the intestine. It opens periodically, allowing the contents of the stomach to move into the duodenum. See also pyloric.
