In response, enteroendocrine cells produce secretin and cholecystokinin (CCK). These hormones enter the circulation. 1) 4) Cholecystokinin stimulates gallbladder smooth muscle contractions to release bile 5) 2) Cholecystokinin causes hepatopancreatic sphincter to relax. Bile and pancreatic juice enter duodenum. Secretin stimulates pancreatic release of alkaline (HCO3-) to neutralize acidic chyme (H+). Cholecystokinin stimulates pancreatic release of: lipases (fat dig.) amylase (carbo dig.) trypsin (protein dig.)
