Important to mix so different regions are exposed: peristalis - contraction, mechanical breakdown, physical process - prepares food for subsequent chemical and/or enzymatic digestion. Chewing: segmentation (small intestine) an additional example: mixes, segmentation is different times/regions of contractions. Changes different point which mixes the food up food with digestive juices.
