Question:

What allows juxtamedullary nephrons to produce more concentrated urine than cortical nephrons?

Inactive
Donna S.
Answer:

Juxtamedullary nephrons produce more concentrated urine due to a longer loop of Henle that extends deeper into the renal medulla. This allows the kidney to remove more water from the filtered blood, producing urine that is more highly concentrated.
