Juxtamedullary nephrons can concentrate salt effectively in the renal medulla because of their long
A) loops of Henle.
B) distal convoluted tubules.
C) Bowman's capsules.
D) proximal convoluted tubules.
E) glomeruli.

Question

Quizplus · Accepted Answer

Juxtamedullary nephrons have long loops of Henle that extend deep into the medulla, allowing for the creation of an osmotic gradient that concentrates salt in the renal medulla. The distal convoluted tubules, Bowman's capsules, proximal convoluted tubules, and glomeruli do not play as significant a role in salt concentration in the medulla.
