Question

Quizplus · Accepted Answer

Segmentation is the major mixing movement in the small intestine. This involves the contraction and relaxation of circular muscles in the intestinal wall, which breaks down food and mixes it with digestive enzymes and secretions. Peristalsis, churning, and ring contractions are also part of the gastrointestinal motility, but they are primarily involved in propulsion and movement of the food through the digestive tract.
