Question

what initiates peristalsis in the small intestine? a.) intestinal juice b.) lleocecal valve c.) motilin d.) segmentation

Explanation:

Motilin is a hormone that plays a crucial role in initiating peristalsis in the small intestine. Intestinal juice aids in digestion, the ileocecal valve controls the flow between the ileum and cecum, and segmentation is a different type of intestinal movement (mixing rather than propulsive like peristalsis).

Answer:

C. Motilin
