i dont know yet

Explanation:

The pyloric sphincter is a ring - shaped muscle at the lower part of the stomach. Its main function is to control the passage of chyme (partially digested food mixed with gastric juices) from the stomach into the small intestine. The internal anal sphincter is related to the anus and defecation. The cardioesophageal sphincter is at the junction of the esophagus and stomach (prevents stomach contents from refluxing into the esophagus). The pancreatic duct is involved in transporting pancreatic juices (not regulating chyme passage). The ileocecal valve is between the ileum (end of the small intestine) and the cecum (beginning of the large intestine).

Answer:

pyloric sphincter
