Quizplus · Accepted Answer

Intestinal churning is a type of segmentation in which the circular layer of smooth muscle contracts and relaxes rhythmically, mixing the chyme and bringing it into contact with the intestinal wall for absorption. Peristalsis is the wave-like movement of longitudinal smooth muscles that propel the chyme forward along the digestive tract. Defecation is the elimination of feces from the rectum through the anus. Deglutition is the process of swallowing food and liquid from the oral cavity into the esophagus.
