The relevant parts of the stomach are the corpus, where food is stored; the antrum, where food is ground; and the pylorus, or pyloric sphincter, the tissue valve that connects to the small intestine.

The antrum grinds and sieves solids, and pumps chyme into the duodenum against pyloric resistance. The timing of antral contractions is related to the frequency of an electrical slow wave ...

The researchers' antrum device consists of a cylinder, capped at one end to imitate a closed pylorus, and a hollow piston that moves inside the cylinder to replicate ACWs.

The relevant parts of the stomach are the corpus, where food is stored; the antrum, where food is ground; and the pylorus, or pyloric sphincter, the tissue valve that connects to the small intestine.

Middle segmental gastrectomy is a small-circumferential gastric resection that preserves the cardia and pylorus, but preserves lymph node station 6 and the longer segment of the pyloric antrum, ...

The pyloric sphincter is a band of smooth muscle that plays an important role in moving the contents of your stomach into your small intestine. It also prevents partially digested food and stomach ...

Researchers have built a prototype artificial lower stomach to gain a deeper understanding of how physical forces influence food digestion based on fluid dynamics. This could aid research in many ...
