Which statement describes the loop of Henle of juxtamedullary nephrons
A)The ascending limb of the loop of Henle is freely permeable to H₂Oa. and NaCl.
B)The filtrate is isotonic as it enters the loop of Henle, hypertonic at the tip of the loop, and hypotonic as it leaves the loop of Henle.
C)The descending limb of the loop of Henle actively transports NaCl out of the tubule and into the interstitial fluid.
D)It is located at the junction of the renal cortex and the medulla.

Question

Quizplus · Accepted Answer

The loop of Henle creates a concentration gradient in the medulla. The filtrate becomes hypertonic at the tip due to water reabsorption in the descending limb and becomes hypotonic as it leaves due to NaCl reabsorption in the ascending limb.
