Which description best differentiates peristalsis from segmentation in the digestive tract?

Peristalsis exclusively occurs in the stomach to churn food while segmentation only occurs in the esophagus to facilitate swallowing

Peristalsis is random contraction for mixing only, whereas segmentation is a continuous unidirectional wave that moves chyme rapidly through the colon

Peristalsis is a coordinated wave of contraction that propels contents distally; segmentation consists of localized contractions that mix luminal contents without unidirectional propulsion

Peristalsis and segmentation are identical processes but use different muscle fiber types in the small and large intestine respectively
