The exit of food from the stomach is regulated by a [[1]] muscle.

The exit of food from the stomach is regulated by a sphincter muscle.

The pyloric sphincter is located at the base of the stomach, where it connects to the small intestine. 

The pyloric sphincter serves as a gateway between the stomach and the small intestine, controlling the release of partially digested food (known as chyme) into the small intestine. 

The sphincter relaxes and contracts periodically to control the flow of chyme, allowing small amounts of food to pass through into the small intestine for further digestion and absorption. 

This helps to regulate the rate of digestion and ensure that the small intestine can handle the amount of food being released from the stomach at any given time.
