what are the roles of pyloric sphincters
Answers
Explanation:
The pyloric sphincter serves as a kind of gateway between the stomach and the small intestine. It allows the contents of the stomach to pass into the small intestine. It also prevents partially digested food and digestive juices from reentering the stomach.
The lower parts of the stomach contract in waves (called peristalsis) that help to mechanically break down food and mix it with digestive juices. This mixture of food and digestive juices is called chyme. The force of these contractions increases in the lower parts of the stomach. With each wave, the pyloric sphincter opens and allows a little bit of chyme to pass into the duodenum.
As the duodenum fills, it puts pressure on the pyloric sphincter, causing it to close. The duodenum then uses peristalsis to move the chyme through the rest of the small intestine. Once the duodenum is empty, pressure on the pyloric sphincter goes away, allowing it to open again.
