Microscopic cross-section of the pylorus.

The pylorus (/paɪˈlɔərəs/ or /pᵻˈlɔərəs/), 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.
