Question

Quizplus · Accepted Answer

The mechanism of water reabsorption by the renal tubules is osmosis. This occurs in the proximal tubule, loop of Henle, distal tubule, and collecting ducts, where water moves passively from areas of high water concentration in the tubules to areas of low water concentration in the blood, driven by the osmotic gradient created by the active transport of solutes like sodium ions out of the tubules and into the blood. There is no solvent drag involved in this process, and although sodium ions are cotransported with other solutes in some segments of the renal tubules, this does not directly affect water reabsorption.
