The Gastroileal Reflex

Question

The gastroileal reflex
A) empties the duodenum.
B) promotes gastric secretion.
C) decreases peristaltic activity.
D) moves some chyme to the colon.
E) is relayed through the CNS.

Accepted Answer

The gastroileal reflex is a reflex pathway that is activated when food is present in the stomach. This reflex causes peristalsis in the ileum (the last part of the small intestine), which moves some chyme (partially digested food) from the ileum to the colon. This helps to make room for more food in the small intestine and promotes continued digestion and absorption in the gastrointestinal tract.
