Secretin and cholecystokinin are secreted in the duodenum. They provide stimulus to
(i) Secretin: Acidic chyme entry into duodenum
(ii) CCK-PZ: Presence of fat in duodenum Their action involves:
(i) Secretin: Releases bicarbonates in the pancreatic juice.
(ii) CCK-PZ: contracts the gall bladder to release bile. Stimulating pancreas to secrete and release digestive enzymes in the pancreatic juice.
