Quizplus · Accepted Answer

A hypertonic solution has a higher concentration of solutes than the surrounding interstitial fluid. When a saline enema, which is a hypertonic solution, is administered, it exerts osmotic pressure and draws fluid from the interstitial space into the colon. This increases the volume in the colon, stimulates peristalsis, and facilitates the evacuation of feces.
