Factor increasing gastric emptying: (A) Presence of fatty food in stomach, (B) Distension of stomach, (C) Presence of tryptophan in stomach, (D) Presence of acid in stomach
Answer is B. Factors affecting increasing Gastric emptying (predominantly neural pathway is involved) Increased food volume in the stomach- gastric distension - stretch receptor activation -promotes increased emptying from the stomach. Type of food: order of gastric emptying is carbohydrate > protein > fat Gastrin has mild to moderate effect on gastrin emptying. Gastric distension and product of protein digestion stimulates gastrin release while acid in stomach inhibits gastrin release.
