Secretin is a hormone produced by:

Secretin is a hormone produced by: Correct Answer Small Intestine

The correct answer is Small Intestine.

Key Points

  • The small intestine is distinguishable into three regions, a ‘C’ shaped duodenum, a long coiled middle portion jejunum and highly coiled ileum.
  • The duodenum secretes an enzyme called the Secretin, it is a polypeptide made up of 27 amino acids
  • Secretin maintains the PH levels in the duodenum and also regulates the secretion of gastric acid 

Functioning of Secretin:

  • When the HCL is released into the intestine from the stomach, the duodenum secretes secretin which stimulates the duct cells of the pancreas
  • The duct cells in turn secrete water & bicarbonate ions, this neutralizes the effect of HCL and the intestinal lining is prevented from getting damaged
