Gastrin.- f. hormone made by the stomach.
Gastrin is a peptide hormone that is secreted by specialized cells called āGā cells that are found in the lining of the stomach. Gastrin released by āGā cells stimulates the stomach to release gastric acid that aids to break down the proteins and absorb certain vitamins.
Secretein - e. stimulates bicarbonate secretion by the pancreas.
Secretin is a peptide hormone that is secreted by specialized cells calledāsā cells that are found in the lining of the duodenum. Secretin hormones are involved in several regulation processes such as regulating secretion in pancreas, liver, and stomach. It helps to stimulate ductal cells of the pancreas to produce bicarbonates.
Bicarbonate.- d. raises pH of chyme.
Initially the pH chyme will be around 1.5 to 3.0. Bicarbonate is released along with the pancreatic juice increases the pH to 7.0. This is done to activate the enzymes in pancreatic juice to break down the food particles...
