Question

The descending limb of the nephron loop is impermeable to water while the ascending limb of the nephron is permeable to water.

Answer 1

Answer: Option B. "False"

Explanation:

Nephron can be defined as the functional unit of the kidney.

Descending limb and ascending limb are the combinly called loop of nephron or henle and are the part of renal tubule in the nephron.

Descending limbs and  ascending limbs have different permeabilities to water and salt that causes high osmolarity in the Medulla.

The thin descending limb is having high permeability to water as they have low permeability to ions and urea while the thick ascending limb has impermeablity to water as there is active reabsorption of ions.

Hence, the correct option is B.
