Which is a correct pairing of sphincter and function?

Question

Quizplus · Accepted Answer

The pyloric sphincter is located at the junction of the stomach and the small intestine, and its function is to control the passage of partially digested food (chyme) from the stomach into the small intestine. The other options are incorrect pairings. The upper esophageal sphincter allows passage of air from the pharynx into the larynx during breathing and prevents food or liquid from entering the airway during swallowing; the ileocaecal sphincter governs the passage of material from the small intestine into the large intestine; the lower esophageal sphincter prevents stomach acid from flowing back into the esophagus and causing heartburn, and the internal anal sphincter controls the release of feces from the rectum during defecation.
