Q. Gastrointestinal hormones secretion and cholecystokinin secreted by duodenum is responsible for the stimulation and contraction of
A) Pancreas and gall bladder
B) Liver, gall bladder and pancreas
C) Gall bladder and cells of gastric glands
D) Salivary glands and gall bladder
Explanation
Secretin and cholecystokinin are the two main gastrointestinal hormones secreted in the duodenum of alimentary canal. Cholecystokinin stimulates gall bladder contraction and hence flow of bile salts is increased into the intestine, while secretin stimulates the release of an alkaline pancreatic fluid, which in turn, neutralises stomach acid
