Final answer:
The correct answer is 'segmented.' While the small intestine uses quick and coordinated movements to mix and propel food, the large intestine uses slower segmented movements primarily for water absorption and forming feces.
Step-by-step explanation:
The segmented movements of the large intestine are slow compared to that of the small intestine. The mechanical digestion in the large intestine includes three types of movements: slow-moving haustral contractions (involve sluggish segmentation), peristalsis (which is slower in the large intestine than in the more proximal areas of the alimentary canal), and mass movements (strong waves pushing content towards the rectum).
Peristalsis in the large intestine is slower than in the small intestine, where it is accompanied by another movement called segmentation. Segmentation mixes chyme with digestive juices and enables more efficient absorption by pushing food particles against the intestinal mucosa.
Unlike the small intestine, where segmentation facilitates absorption by mixing food residues, the large intestine engages in slower segmental movements primarily for water absorption and preparing waste for elimination.
