What is a feature of laxative types?

Laxative types are categorized based on their mechanisms of action and the effects they have on the bowel. The correct answer highlights that laxatives include bulk-forming, saline, and stimulant types, which are the main categories used to promote bowel movements.

Bulk-forming laxatives work by absorbing water in the intestines, forming a gel-like substance that adds bulk to the stool and helps it to pass more easily. Saline laxatives draw water into the intestines, increasing fluid in the bowel to create a bowel movement. Stimulant laxatives work by directly stimulating the intestinal walls to increase peristalsis, which moves the stool through the colon.

The other options do not accurately represent the function or classification of laxatives. Inhibiting inflammatory cells relates primarily to medications that reduce inflammation rather than those that promote bowel movements. Enhancing airway relaxation pertains more to bronchodilator medications used in respiratory conditions, and neutralizing stomach acid is the function of antacids, not laxatives. Understanding these distinctions is crucial in recognizing the therapeutic uses of various medications.
