MEDICAL PHYSIOLOGY

Detailed explanation-1: -Among the various peptides, so far investigated, gastrin inhibits the emptying rate, however, this effect is only seen at unphysiological high concentrations. Cholecystokinin, on the other hand, is able to decrease the delivery of glucose to the duodenum at physiological concentrations.

Detailed explanation-2: -Stomach motility and gastric emptying Gastric emptying is also inhibited when nutrients enter the small intestine. This regulation-called feedback control-already happens in the duodenum where it is called the “duodenal brake.” Calorific food slows gastric emptying more than non-calorific gum cellulose.
