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.
The first hormone discovered was adrenaline, also known as epinephrine. It was discovered in 1894 by Polish physiologist Napoleon Cybulski. Adrenaline is produced by the adrenal glands and plays a key role in the body's response to stress and danger.
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 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.

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 that controls the secretions into the duodenum, and also separately, water homeostasis throughout the body. It is produced in the S cells of the duodenum in the crypts of Lieberkühn. Its effect is to regulate the pH of the duodenal contents via the control of gastric acid secretion and buffering with bicarbonate from the centroacinar cells of the pancreas as well as intercalated ducts. It is notable for being the first hormone to be identified. In humans, the secretin peptide is encoded by the SCTgene.
Gastrin and CCK cause the gall bladder to contract causing bile to be released. Secretin alters the volume of bile being produced. They also have various effects on the pancreas and stomach.
The duodenal wall produces the hormones secretin and cholecystokinin (CCK). Secretin stimulates the pancreas to release bicarbonate to neutralize stomach acid, while CCK stimulates the gallbladder to release bile and the pancreas to release digestive enzymes in response to the presence of fatty acids and amino acids in the duodenum.
The first hormone discovered was adrenaline, also known as epinephrine. It was discovered in 1894 by Polish physiologist Napoleon Cybulski. Adrenaline is produced by the adrenal glands and plays a key role in the body's response to stress and danger.
