Quizplus · Accepted Answer

A saline enema solution is hypertonic, which means it has a higher concentration of solutes than the interstitial fluid. As a result, it exerts an osmotic pressure and draws fluid from the interstitial space into the colon. This increased volume in the colon stimulates peristalsis and leads to the evacuation of stool.
