Pyloric sphincter
The ringlike muscle at the base of the stomach that controls the flow of partially digested food into the duodenum of the small intestine is called the pyloric sphincter. It regulates the passage of chyme from the stomach to the small intestine, ensuring that food is released in a controlled manner for further digestion and absorption. This muscle plays a crucial role in the digestive process by preventing backflow and allowing for optimal nutrient breakdown.

A ringlike muscle that tightly constricts the opening of a passageway is called a sphincter. Sphincters are found throughout the body, including the digestive and urinary systems, where they control the flow of substances by opening and closing. They play a crucial role in regulating bodily functions and maintaining homeostasis.
