Quizplus · Accepted Answer

Reabsorption is the process by which the kidneys return water and other essential substances (such as glucose, amino acids, and ions) from the filtrate (fluid that has been processed by the kidneys) back into the bloodstream. This allows the body to retain what it needs and avoid losing too much valuable material through urine.
