What is gastrocolic reflex?

Reflex. It's the body's reflex controlling the motility, or peristalsis, of the gastrointestinal tract. It involves an increase in motility of the colon in response to stretch in the stomach & byproducts of digestion in the small intestine. It's responsible for the urge to defecate following a meal. The small intestine shows a similar motility response. The gastrocolic reflex helps make room for more food.
