Explanation: 

Detailed explanation-1: -Glucagon retards gastric emptying of liquids and inhibits motility throughout the gastrointestinal tract [63].

Detailed explanation-2: -Somatostatin is a potent inhibitor of gastrin-stimulated acid secretion by activation of somatostatin receptor type 2 (sst2) in vivo, probably in part by blocking gastrin-stimulated histamine release from enterochromaffin-like cells expressing sst2.

Detailed explanation-3: -9, 38 Gastrin has been reported to delay gastric emptying despite producing an increase in antral contractility. 10 Gastric acid suppression may affect gastric motility and emptying by other mechanisms also.
