Secretin is a hormone produced in the intestines that promote the release of insulin from pancreatic islet cells.
Discussion about secretin:
- When fatty acids and acidic chyme are present, secretin is released. It performs a number of functions by attaching to secretin receptors, the majority of which are related to digestion and acid neutralization.
- In its principal function, secretin tells the pancreas to release bicarbonate ions into the pancreatic juice, raising the pH to between 8 and 8.3 in order to neutralize the acidic chyme. The pancreatic juice's digesting enzymes may function at their best as a result, safeguarding the duodenum's lining.
- Additionally, secretin controls the pyloric sphincter's tightness, gastrin release, HCl synthesis, and small intestine motility.
As a result, secretin also encourages the pancreas to produce more insulin in response to ingesting glucose.
