explain the regulation of secretions of the small intestine
Sucrase is a family of enzymes. Some of it is secreted from the salivary glands in the mouth but most of the sucrase activity is in the small intestines. In the intestines it is not secreted, but rather, contained in the wall.
the bile is secreted in the small intestines of the body. from the liver
Sucrase is secreted by the brush border cells of the small intestine, specifically the duodenum and the jejunum. It is an enzyme involved in breaking down sucrose into its simple sugar components, glucose and fructose, for absorption into the bloodstream.
The secrete gastric juice and the digestive hormones are secreted from the small intestines during the digestion process.
Bile is made in the liver and secreted into the Small intestines to neutralize the acidity of the chyme leaving the stomach. When there is no food entering the small intestines Bile is stored in the Gallbladder until it is needed.
Renin is the enzyme secreted by the juxtaglomerular apparatus.
Bile is made in the liver and secreted into the Small intestines to neutralize the acidity of the chyme leaving the stomach. When there is no food entering the small intestines Bile is stored in the Gallbladder until it is needed.
An enzyme secreted by pancreatic cells is most likely targeted to the digestive system, specifically the small intestine. It enters the small intestine through the pancreatic duct to aid in the digestion and breakdown of nutrients in food.
Renin
Lipase is a digestive enzyme that in humans is secreted primarily by the pancreas. Its function is to break down fats in the digestive system into fatty acids and other components that can be absorbed by the intestines.
Carboxypeptidase is secreted by Pancreas in inactive form (procarboxypeptidase) and is activated by trypsin. Carboxypeptidase is also secreted by small intestine as brush border enzyme. Reference: Human Anatomy and Physiology by Elaine N. Marieb
The small intestine contains all the enzymes that has been secreted by the pancreas and the liver. These may include: nuclease, pancreatic amylase, lipase, trypsin, bile (which is actually salt), and some bicarbonates (again, not really an enzyme) to neutralize the stomach acid.
