Explanation:
Detailed explanation-1: -The presence of fat, such as oleate, in the meal results in stimulation of cholecystokinin (CCK) secretion in the duodenum; in turn, this inhibits antral motility, stimulates pyloric tone and delays gastric emptying [8]. CCK is the first of a repertoire of hormones that regulate gastric emptying.
Detailed explanation-2: -Cholecystokinin stimulates the gallbladder to contract and release stored bile into the intestine.
