Solution

The process that returns water to the blood from the filtrate is primarily Osmosis. This process occurs in the kidneys during the filtration and reabsorption phases. In the nephron, specifically within the loop of Henle and the collecting ducts, water is reabsorbed back into the bloodstream through osmosis, driven by the osmotic gradient created by the surrounding interstitial fluid.

Explanation:

  1. Active Transport: This is a process that moves substances against their concentration gradient, often involving energy expenditure, but it is not the primary mechanism for water reabsorption.

  2. Osmosis: This is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration, which is essential for reclaiming water from the filtrate in the kidneys.

  3. Carrier Transport: While this involves proteins that help substances cross cell membranes, it does not specifically pertain to the passive movement of water.

  4. Counter Current Exchange: This is a mechanism that occurs in the kidneys to maximize reabsorption of solutes and water, but it is not specifically the process that directly returns water to the blood.

Final Answer

Osmosis is the correct choice for the process that returns water to the blood from the filtrate.
