Cholecystokinin (gastric emptying) • CCK also regulates gastric emptying. • Distended duodenum and fatty acids or undigested proteins in the chyme promote the secretion of CCK. • CCK triggers the closing of the pyloric sphincter, thereby inhibiting gastric emptying. • High-protein and high-fat meals stimulate the secretion of CCK and consequently take longer to digest and empty.
