Detailed explanation-1: -The enterogastric reflex is stimulated by duodenal distension. It can also be stimulated by a pH of 3-4 in the duodenum and by a pH of 1.5 in the stomach. Upon initiation of the reflex, the release of gastrin by G-cells in the antrum of the stomach is shut off.
Detailed explanation-2: -The secretion is blocked by cholinergic inhibition, suggesting a gastropancreatic vagovagal reflex [117]. When gastric juice and contents of a meal enter the duodenum, a variety of intraluminal stimulants can act on the intestinal mucosa to stimulate pancreatic secretion through both neural and humoral mechanisms.
Detailed explanation-3: -Secretin stimulates the secretion of bicarbonate-rich pancreatic fluid. [11] Secretin enters the intestinal lumen and stimulates bicarbonate secretion, ultimately neutralizing gastric H+, which plays an essential role in fat digestion by creating a more neutral (pH 6 to 8) environment.
Detailed explanation-4: -In order to neutralize the acidic chyme, a hormone called secretin stimulates the pancreas to produce alkaline bicarbonate solution and deliver it to the duodenum.
