Which regulates the passage of food from the stomach to the duodenum?Multiple choice question.Esophageal sphincterPyloric sphincter

Correct Option

The correct answer is Pyloric sphincter.

Explanation

The pyloric sphincter is a muscular valve located at the lower end of the stomach that regulates the passage of partially digested food, known as chyme, from the stomach to the duodenum, the first section of the small intestine. It opens to allow the chyme to enter the duodenum and closes to prevent backflow into the stomach. In contrast, the esophageal sphincter, specifically the lower esophageal sphincter, regulates the passage of food from the esophagus into the stomach. Thus, the pyloric sphincter is the correct choice for the regulation of food passage from the stomach to the duodenum.
