Which of the following muscles regulates the exit of food from the stomach into the small intestine?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Pyloric Sphincter.
The exit of food from the stomach into the small intestine is regulated by the pyloric sphincter, a muscular ring located at the junction between the stomach and the duodenum. It's situated at the bottom of the stomach, where it connects to the duodenum, the first part of the small intestine. The pyloric sphincter ensures that food is properly mixed with digestive enzymes before moving to the next stage of digestion.
