Quizplus · Accepted Answer

The thick ascending limb of the nephron loop actively pumps out sodium and chloride ions into the peritubular fluid, which helps to establish the concentration gradient responsible for reabsorption of water and other solutes further along the nephron. This process is known as active transport. The other options listed are not actively transported by the thick ascending limb.
