Expert Answer:

Pylorus is a cone-shaped constriction in the gastrointestinal tract that demarcates the end of the stomach and the beginning of the small intestine. Pylorus is the connection between stomach and duodenum.

(The main functions of the pylorus are to prevent intestinal contents from reentering the stomach when the small intestine contracts and to limit the passage of large food particles or undigested material into the intestine.)
