b. |
gastroileal |
|
c. |
gastrocolic |

gastrocolic reflex in large intestine: mass movements often tend to be triggered by meals, as the presence of chyme in stomach and deodenum promptes them .this overall process is called gastrocolic reflex.
A) enterogastric : it is a nervous reflex where by stretching of the wall of the deodenum results in inhibition of gastric motility and reducing rate of emptying of the stomach.
