The chyme moves through the sections of the small intestine via two types of contractions. Segmentation is a stationary constriction of the smooth muscle in ring like patterns. This type of contraction further churns the chyme, mixing in the bile and digestive enzymes to finish chemical digestion. It also allows for maximum contact between chyme and the villi, facilitating maximum absorption of nutrients. Once the chyme has churned and mixed with the bile and digestive enzymes, it continues to move through the jejunum and ileum through peristalsis.
