Quizplus · Accepted Answer

Swallowing causes the fundus to relax (receptive relaxation) to receive a bolus of food from the esophagus. Relaxation is coordinated by efferent, nonadrenergic, noncholinergic vagal fibers and is facilitated by gastrin and cholecystokinin, two polypeptide hormones secreted by the gastrointestinal mucosa. Progesterone is a sex hormone not involved in gastrointestinal function. Glucagon is released by the pancreas when blood sugar gets too low. Motilin stimulates gastric emptying.
