Explanation:
Detailed explanation-1: -The gastrocolic reflex is a physiological reflex that controls the motility of the lower gastrointestinal tract following a meal. As a result of the gastrocolic reflex, the colon has increased motility in response to the stretch of the stomach with the ingestion of food.
Detailed explanation-2: -Gastric phase ("full steam ahead"): When a meal enters the stomach several additional factors come into play, foremost among them distension and mucosal irritation. Distension excites stretch receptors and irritation activates chemoreceptors in the mucosa.
