Quizplus · Accepted Answer

The loop of Henle uses a countercurrent multiplication mechanism to concentrate urine. This involves the active transport of ions by the ascending limb of the loop of Henle, and the passive diffusion of water out of the descending limb of the loop, creating a concentration gradient that increases as the urine moves through the loop.
