Pylorus

The pylorus is part of the digestive system.

Function of the pylorus

The function of the pylorus is to transfer chyme (the food digested by the stomach) from the stomach to the duodenum. It regulates the emptying of the stomach in small amounts by means of a potent sphincter.

Structure of the pylorus

The pylorus is located between the stomach and duodenum and is composed of smooth muscles that make peristaltic movements. It is divided into two parts: the antrum, which is connected to the stomach, and the canal connected to the duodenum. The pyloric sphincter lies between these two parts.
