The soft and formless dejectionwith an irregular surface, in contrast withone formed with marks, or more particu-larly with one of marks and units too,must have some meaning. Such pronouncedfeatures in two of the types must be dueto some of the functions of the gut; andin order to compare these features withthe actions, it is well to review the intes-tinal motility. In general there are threeessential forms of motility; rhythmic seg-mentation in the small intestine, peristalsis. Fig. 8. A diagram of the intestines illustrating the threemost essential forms of motility: rhythmic seg-mentation in the small gut, peristalsis and anti-peristalsis in the proximal eolon and haustralsegmentation in the distill colon. and ;intiperistalsis in the proxim;iI colon,and haustral churning or segmentation inthe distal colon. These functions areshown diagrammatically in Figure 8.
