Question

Quizplus · Accepted Answer

Dehydration is prevented by the process of tubular reabsorption, which returns about 99% of the filtrate back to the blood. The juxtaglomerular apparatus and renal artery are not directly involved in this process. Tubular secretion is a separate process that involves the movement of substances from the blood into the renal tubules, and is not directly related to dehydration prevention.
