ANSWER
B. Pyloric sphincter
B is indeed the function that the question describes. Sphincter of Oddi functions in allowing digestive juices (bile) through the hepatopancreatic duct. Cardiac sphincter functions between the esophagus and the stomach, preventing stomach juice (acid) from coming up the esophagus. The Ileocecal sphincter borders the small and large intestine, preventing contents from the colon spilling back into the ileum (small intestine). The esophageal sphincter functions in opening to allow food from the mouth to enter the esophagus. It is very important to know and understand the functions of these main sphincters in the body.
