Detailed explanation-1: -Segmentation, also known as haustration occurs in the large intestine Segmentation moves food backwards and forwards in a local intestinal segment. This type of intestinal motility enhances mixing of the food with enzymes and mucus.

Detailed explanation-2: -Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Detailed explanation-3: -Segmentation activates circular muscles in your intestines that contract to move food back and forth, a bit like the churning of a washing machine. This churning gives food in the intestines a chance to mix with gastric juices and helps break it down into smaller pieces for digestion.

Detailed explanation-4: -Segmentation, which occurs mainly in the small intestine, consists of localized contractions of circular muscle of the GI tract. These contractions isolate small sections of the intestine, moving their contents back and forth while continuously subdividing, breaking up, and mixing the contents.
