Question

the major mixing movement in the small intestine is accomplished by

multiple choice

segmentation

mass movement

churning

peristalsis

Explanation:

Segmentation contractions in the small intestine are rhythmic local constrictions that mix chyme with digestive juices and bring food into contact with the mucosa for absorption. Mass movement is more associated with the large intestine. Churning occurs in the stomach. Peristalsis is more for propulsion (though it also occurs in the small intestine, segmentation is the major mixing movement).

Answer:

segmentation
