Question

Quizplus · Accepted Answer

Stenosis (constriction) of the pyloric sphincter would interfere with passage of chyme into the duodenum. The pyloric sphincter is the valve that regulates the emptying of the stomach contents (chyme) into the small intestine (duodenum). Constriction or narrowing of this valve can lead to obstruction of the passage of chyme into the duodenum, causing symptoms such as nausea, vomiting, and abdominal pain.
