Best stimuli for pancreatic secretion rich in electrolytes ?
High-Yield Explanation
Secretin increases the secretion of bicarbonate by the duct cells of the pancreas and biliary tract. It thus causes the secretion of a watery, alkaline pancreatic juice. Its action on pancreatic duct cells is mediated cAMP. It also augments the action of CCK in producing pancreatic secretion of digestive enzymes. It decreases gastric acid secretion and may cause contraction of the pyloric sphincter. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012). Chapter 25.
