Title: Re: Explain the function and actions of peristalsis and segmentation. Post by: padre on Aug 11, 2013 These are the two primary types of muscle contractions that move food through the GI tract. Both are forms of mechanical digestion. Peristalsis moves food forward through the esophagus and stomach. It mixes and churns the stomach contents with gastric juices until the food is liquefied. Segmentation begins in the small intestine, breaking food into smaller pieces and combining it with digestive juices. It continues in the large intestine, moving food slowly through the colon and allowing water to be absorbed.
