Which valve is located between the ileum and the cecum?

Explanation:
The valve between the ileum and the cecum is the ileocecal valve. It sits right at the junction where the small intestine ends and the large intestine begins, acting as a muscular sphincter that regulates the passage of chyme from the ileum into the cecum. It opens to allow small, controlled amounts of material to move forward with peristaltic waves and closes to prevent backflow from the large intestine into the ileum, helping to maintain separate environments for digestion and absorption in the two segments. The other options aren’t located at this boundary: the valve at the junction of the stomach and small intestine is the pyloric valve; the valves between heart chambers are the atrioventricular valves; and the lower esophageal region has a sphincter sometimes called the cardiac sphincter.
