CCK- slows down the emptying of food, stimulates the production of bile in the liver as well as its release from the gall bladder into the duodenum. Secretin - involves production of pancreatic fluid thats low in enzyme content and high in bicarbonate GIP- decreases peristalsis and slows passage of chyme into the duodenum
