Quizplus · Accepted Answer

The pyloric sphincter is located at the lower end of the stomach and regulates the passage of food from the stomach to the duodenum. The cardiac sphincter controls the entry of food into the stomach from the esophagus, while the anal sphincter controls the release of feces from the rectum. There is no such sphincter as the duodenal sphincter.
