Question

Quizplus · Accepted Answer

Long nephron loops, which are characteristic of juxtamedullary nephrons, enable the kidney to concentrate urine more effectively. This is because they create a deep osmotic gradient in the medulla, allowing for greater water reabsorption from the collecting ducts, leading to more concentrated urine.
