Explain the Mechanism of Action of the Emollient Laxatives

Explain the mechanism of action of the emollient laxatives.

A) The emollient laxatives work by releasing carbon dioxide gas. The gas pushes against the rectum wall, inducing muscle contraction and stool movement.
B) The emollient laxatives are natural fibers or grains that remain in the intestine, soak up water, and expand. The water, which is retained, softens the stool, and the swelling action distends the rectum and initiates defecation.
C) The emollient laxatives are a mixture of sodium and magnesium salts. These ions attract water, which causes a more liquid stool to be formed.
D) The emollient laxatives act on the stool to permit water to penetrate the fecal mass. The oily nature of these laxatives eases the passage of the stool through the rectum.
