Secretin stimulates secretion of bicarbonate from
-
Liver
-
Kidneys
-
Pancreas
-
Stomach
Secretin hormone is secreted by and stimulates
-
Duodenum - pancreas
-
Duodenum - liver
-
Stomach - gastric glands
-
Thyroid - thyroid
Secretin is secreted in duodenum and stimulates the secretion of pancreatic juice but inhibits the secretion of gastric juices. It is released in response to acid in the small intestine, and stimulates the pancreas and bile ducts to release a flood of bicarbonate base, which neutralizes the acid.
So, the correct answer is 'Duodenum - pancreas'.
Select the correct match.

Cholecystokinin, previously called pancreozymin, is synthesized by I-cells in the mucosal epithelium of the small intestine and secreted in the duodenum. It is responsible for stimulating the digestion of fat and protein. Secretin is a peptide hormone that regulates water homeostasis throughout the body, and influences the environment of the duodenum by regulating secretions in the stomach and pancreas. Secretin is produced in the S cells of the duodenum, which are located in the crypts of Lieberkuhn.
