Visceral motility is responsible for transporting the contents of the different organs. Thus it controls the amount of contents found in any organ at any one time. Through contraction and dilatation mechanisms, the food bolus passes through the intestinal tract, the gall bladder secretes bile, urine is excreted, semen is transported and the uterus wall contracts during birth.

This motility is also responsible for the closing of sphincters, for example at the stomach exit (pylorus) or in the bladder. The diastole and systole of the heart can be understood as the motility of the circulatory system.
