Where in the body is secretin produced?
Secretin is produced in the small intestine, specifically in the duodenum. It is released in response to acidic chyme entering the duodenum from the stomach, and it helps stimulate the pancreas to release bicarbonate-rich fluids to neutralize the acidity.
Is secretin an enzyme or a hormone?
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.
What stimulates release of enterokinase?
The release of enterokinase is stimulated by the presence of acidic chyme in the small intestine. This triggers the release of enterokinase from the duodenal mucosal cells, which then activates trypsinogen to trypsin in the small intestine.
What stimulates the hormone cholecystokinin from the intestinal wall?
This is a digestive hormone released with secretin when food from the stomach reaches the first part of the small intestine. It is made by some of the cells lining the first part of the small intestine.
Which digestive secretions functions as a chemical messenger?
The hormone secretin functions as a chemical messenger in the digestive system. It is released by the duodenum in response to the presence of acidic chyme, and it stimulates various organs like the pancreas to release bicarbonate to neutralize the acidity in the small intestine.
Secretin and cholecystokinin are hormones produced in the?
Small intestine

What is the of secretin?
It inhibits the secretions of the stomach.
How does the secretin helps to proctect the small intesine for the acidic chyme?
Secretin is a hormone released by the small intestine in response to acidic chyme entering from the stomach. It stimulates the pancreas to release bicarbonate-rich pancreatic juice, which helps neutralize the acidity of the chyme, creating a more optimal pH environment for digestion in the small intestine. This process protects the small intestine from damage caused by the acidic chyme.
What stimulates release of enterokinase?
The release of enterokinase is stimulated by the presence of acidic chyme in the small intestine. This triggers the release of enterokinase from the duodenal mucosal cells, which then activates trypsinogen to trypsin in the small intestine.
The hormone secretin responds to food entering the small intestine and stimulates the pancreas to release what?
Bicarbonate.
What is the target organ for hormone secretin?
the stomach, pancreas, small intestine and gallbladder
A hormone that stimulates pancreatic secretions?

How do the intestines work?
The small intestine is where most chemical digestion takes place. Most of the digestive enzymes that act in the small intestine are secreted by the pancreas and enter the small intestine via the pancreatic duct. The enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in the small intestine in response to the presence of nutrients. The hormone secretin also causes bicarbonate to be released into the small intestine from the pancreas in order to neutralize the potentially harmful acid coming from the stomach.
What is the Pathway of bile from gallbladder to duodenum?
Bile is produced in the liver, stored in the gallbladder, and released into the duodenum. When fats are detected in the duodenum, the hormone cholecystokinin triggers the gallbladder to contract, releasing bile into the small intestine through the common bile duct. From there, bile helps with the digestion and absorption of fats in the small intestine.
What hormone causes an increased output of enzyme-rich pancreatic juice and stimulates gallbladder contraction to release bile?
Bilirubin is used by the liver, to make bile
