GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Once the chyme is well mixed, waves of muscle contractions propel it through a valve called the pylorus and into the upper section of your small intestine (duodenum). The pylorus might release about an eighth of an ounce (about 4 milliliters) of chyme at a time.

Detailed explanation-3: -The ileocecal valve, located at the opening between the ileum and the large intestine, controls the flow of chyme from the small intestine to the large intestine. The first part of the large intestine is the cecum, a sac-like structure that is suspended inferior to the ileocecal valve.
