It inhibits the secretions of the stomach.
The gastrin, secretin, and cholecystokinin
cholecystokinin and secretin
Secretin is a hormone produced by the S cells of the duodenum in response to acidic chyme entering the small intestine from the stomach. Its primary function is to stimulate the pancreas to release bicarbonate-rich fluid, which helps neutralize stomach acid, creating an optimal pH for digestive enzymes in the intestine. Additionally, secretin promotes bile production in the liver and regulates gastric acid secretion, contributing to overall digestive processes.
SECRETIN
Secretin is a hormone, not an enzyme. It is produced by the duodenum in response to the presence of acid in the stomach, and it helps to stimulate the release of bicarbonate-rich pancreatic juices to neutralize the acid entering the small intestine.
Secretin is a hormone released by the small intestine. Like insulin, the presence of food in the stomach triggers it to release secretin which in turn triggers the pancreas and liver to release bile and pancreatic juice for food breakdown and absorption.
When highly acidic chyme enters the duodenum, the hormone secretin is released. Secretin stimulates the pancreas to release bicarbonate-rich fluids to neutralize the acidity of chyme coming from the stomach.

Small intestine
Yes, secretin and gastrin can be considered antagonistic in their functions. Secretin, which is produced in response to acidic chyme in the small intestine, stimulates the pancreas to release bicarbonate and inhibits gastric acid secretion. In contrast, gastrin is produced by the stomach in response to food intake, promoting gastric acid secretion to aid digestion. Thus, while gastrin encourages gastric activity, secretin acts to moderate it.
Gastrin, secretin, and cholecystokinin are examples of hormones that play roles in the regulation of the digestive system. Gastrin stimulates gastric acid secretion, secretin stimulates pancreatic bicarbonate secretion, and cholecystokinin stimulates gallbladder contraction and pancreatic enzyme secretion.
It stimulates the liver to secrete bile.
