<prompt> Factor increasing gastric emptyingPresence of fatty food in stomachDistension of stomachPresence of tryptophan in stomachPresence of acid in stomach  <response>: 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.
