Editing Peristalsis (section)

===Small intestine===
Once processed and digested by the stomach, the semifluid chyme is passed through the [[pyloric sphincter]] into the [[small intestine]]. Once past the stomach, a typical peristaltic wave lasts only a few seconds, traveling at only a few centimeters per second. Its primary purpose is to mix the chyme in the intestine rather than to move it forward in the intestine. Through this process of mixing and continued digestion and absorption of nutrients, the chyme gradually works its way through the small intestine to the [[large intestine]].<ref name="ReferenceA"/>

In contrast to peristalsis, [[segmentation contractions]] result in that churning and mixing without pushing materials further down the digestive tract.
