Quizplus · Accepted Answer

The descending limb of the loop of Henle is permeable to water, which allows for water to leave the tubule and be reabsorbed into the bloodstream. It is not permeable to sodium, which helps to maintain the concentration gradient necessary for the reabsorption of water in the ascending limb of the loop of Henle.
