Which reflex is triggered by food in the stomach, relaxes the ileocecal valve, and allows residue into the cecum?
kari74 [83]

Gastroileal reflex is triggered by food in the stomach, relaxes the ileocecal valve, and allows residue into the cecum.

The gastroileal reflex is triggered by the presence of food in the stomach as well as gastric peristalsis.

Gastroileal reflex brings about peristalsis in the ileum as well as the opening of the ileocecal valve, which in turn facilitates the emptying of the ileal constituents into the large intestine or colon.

The gastroileal reflex is one among the three extrinsic reflexes of the gastrointestinal tract. The other two include the gastrocolic reflex as well as the enterogastric reflex.

This type of gastrointestinal reflex is moderated by the vagus nerve and gastrin.
