Quizplus · Accepted Answer

Stimulant laxatives act directly on the intestine, causing an irritation that promotes peristalsis and evacuation.Saline laxatives draw water into the bowel to facilitate the passage of feces.Lubricant laxatives lubricate the intestinal wall and soften the stool, allowing a smooth passage of fecal contents.Bulk producing laxatives must be administered with a full glass of water.The laxative causes water to be retained within the stool.This increases bulk, which stimulates peristalsis.
