Current Question (ID: 14161)

Question:

A mass peristaltic movement is responsible for:-

Options:

1. Release of bile and pancreatic juice into the duodenum
2. Passage of chyme from stomach to duodenum
3. Vomiting
4. Defecation

Solution:

During a mass peristaltic movement, a wave of muscular contractions moves along a section of the colon, pushing the feces towards the rectum. This movement typically occurs after a meal and can result in the urge to defecate. Release of bile and pancreatic juice into the duodenum is regulated by the action of the hormone cholecystokinin (CCK) and does not involve peristaltic movements. The passage of chyme from the stomach to the duodenum is regulated by the opening and closing of the pyloric sphincter and involves regular peristaltic movements. Vomiting is a reflex that involves the reverse movement of food and liquid from the stomach out through the mouth, and it is not a peristaltic movement.
