In biology, motility is the ability of organisms and fluid to move or get around. A microbiologist might test and compare the motility of various single-celled organisms. An easy way to remember that motility means the ability to move without help is the mot- at the root of the word. It's the same root that's found in motor, which is, of course, the engine that drives a car. If you've got good motility then your motor is working.

A motility disease is one that involves changes in the way the stomach contracts.ynchronized contractions and motility of the abomasal wall and the opening of the pyloric sphincter are dependent on the fullness of the abomasum, the degree of trituration and the pH of the contents and the integrity of the vagal and sympathetic nerve supplies. intestinal motility.
