Is the ringlike muscle at the base of the stomach that controls flow of partially digested food from the stomach to the duodenum of the small intestine?

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.
