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.

May 18, 2015 · In collaboration with physiologist W. M. Bayliss, English physician E. H. Starling discovered secretin in 1902.[1] During that era, hormonal control of pancreatic secretions conflicted with the teachings of the Pavlov school that only neural reflexes were involved in pancreas response to duodenal acidification.[2] The findings of Bayliss and Starling remain as a scientific truth, but ...

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. It was discovered in 1902 by …

Dec 1, 2012 · Secretin is secreted by S cells in the small intestine and affects the function of a number of organ systems. Secretin receptors (SR) are expressed in the basolateral domain of several cell types.

Mar 15, 2023 · Human secretin is a 27 amino-acid peptide, with a molecular weight of 3055 D. Its sequence is conserved across many mammalian species (figure 1). Similar to other gastrointestinal peptides, secretin is amidated at the C-terminus. It is the founding member of the secretin/glucagon/vasoactive intestinal polypeptide family of gastrointestinal ...

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).

Jul 22, 2023 · Explore the physiology and role of secretin, a hormone involved in digestion. Learn about its production, secretion, target organs, and its impact on pancreatic secretion, bicarbonate secretion, and gallbladder contraction.

Dec 15, 2022 · 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 functions as a type of fireman: it is released in response to acid in the small intestine, and stimulates the pancreas and bile ducts to release a flood of bicarbonate base, which neutralizes the acid.

Secretin is a gastrointestinal hormone primarily used to examine pancreatic secretion during endoscopic procedures. It is also considered to act as a neuropeptide or brain-gut stress regulatory hormone that affects levels of γ-amino butyric acid in the brain.
