What is pyloric pump?

The pyloric pump is a muscular valve located between the stomach and the small intestine, specifically at the junction of the pylorus of the stomach and the duodenum of the small intestine. Its main function is to regulate the flow of partially digested food from the stomach into the small intestine. The pyloric pump contracts and relaxes to control the release of chyme (partially digested food) into the small intestine for further digestion and absorption. Dysfunction of the pyloric pump can lead to issues such as gastroparesis or delayed gastric emptying.
