what is the primary function of the pyloric valve?

The primary function of the pyloric valve (or pyloric sphincter) is to act as a valve controlling the passage of partially digested food (chyme) from the stomach into the small intestine (duodenum). It allows small amounts of chyme to pass through at a time, ensuring the small intestine can properly digest and absorb nutrients. Additionally, it prevents the backflow of intestinal contents into the stomach. This regulation occurs through coordinated muscle contractions and nervous system control, allowing digestion to proceed in a controlled and efficient manner.
