Question

Quizplus · Accepted Answer

The proximal tubule is responsible for the reabsorption of approximately 65-70% of the filtered water, making it the site where the most water is reabsorbed in the kidney. This process occurs regardless of the body's hydration status and is not directly influenced by antidiuretic hormone (ADH) levels.
