Secretin - Wikipedia
Secretin is a hormone that regulates water homeostasis throughout the body and influences the environment of the duodenum by regulating secretions in the stomach, pancreas, and liver. It is a peptide hormone produced in the S cells of the duodenum, which are located in …
Physiology, Secretin - StatPearls - NCBI Bookshelf
2023年5月1日 · Secretin is a peptide hormone composed of 27 amino acids. The sequence is like that of a gastric inhibitory peptide (GIP), vasoactive intestinal peptide (VIP), and glucagon. Secretin is produced in the duodenal mucosa and acts on the pancreas where it stimulates the release of bicarbonate and water.
Secretin | Definition & Function | Britannica
Secretin, a digestive hormone secreted by the wall of the upper part of the small intestine (the duodenum) that regulates gastric acid secretion and pH levels in the duodenum. Secretin is a polypeptide made up of 27 amino acids.
The physiological roles of secretin and its receptor - PMC
2012年12月1日 · In this review, we discuss the role of secretin in the regulation of heart function, which acts not only a hormone, but also as a neurotransmitter or neuromodulators . Generally speaking, secretin effects are mediated by activation of cAMP synthesis that is decreased during cardiac pathologies.
Secretin: Understanding the Physiology and Role in Digestion
Secretin is a hormone involved in the regulation of digestive processes in the human body. This comprehensive article aims to explore the physiology of secretin, including its production, secretion, target organs, and the role it plays in digestion and overall gastrointestinal function.
Secretin: Definition, Function, Health Effects & Interactions
2022年12月15日 · Secretin is a hormone that improves digestion while protecting the stomach and the gut. Abnormal secretin levels may be diagnostic of pancreatic disorders; this hormone also has an impact on fluid balance, other digestive hormones, the heart, brain, and lungs.
Secretin: An Old Hormone with a Burning Secret - PMC
Secretin is a 27-amino-acid polypeptide secreted by the duodenum that inhibits gastric acid secretion and stimulates pancreatic bicarbonate production. In this issue of Cell, Li et al. (Li et al., 2018) now propose a new function for this digestive hormone, the first hormone ever discovered in 1902 (Bayliss and Starling, 1902). The authors ...
Secretin and the exposition of hormonal control - PMC
2004年10月10日 · Our understanding of secretin and pancreatic secretions has developed. However, the salient findings of Bayliss and Starling concerning secretin have stood the test of time. Thus secretin is recognized as the key pathway mediating a now classical negative feedback reflex.
Secretin - an overview | ScienceDirect Topics
Secretin is a 27–amino acid endocrine hormone secreted from the epithelium of the upper small intestine in response to low pH and the presence of nutrient digestive products.
Secretin - an overview | ScienceDirect Topics
Secretin was the first peptide hormone discovered. The principal biological action of secretin is to stimulate the release of bicarbonate and water from pancreatic acinar cells. Secretin has also been shown to regulate bicarbonate secretion from cholangiocytes to maintain bile homeostasis.
