Question

Which of the following is most permeable to water?

• A. Thin ascending Loop of Henle
• B. Distal convoluted tubule
• C. Thin descending Loop of Henle
• D. Cortical portion of collecting tubule

Answer 1

The correct option is C Thin descending Loop of Henle

The nephron is the structural and functional unit of the kidney. Its body is composed of the renal corpuscle, proximal convoluted tubule (PCT), Henle's loop and distal convoluted tubule (DCT). The descending limb of Henle's loop is permeable to water and impermeable to electrolytes and ascending limb is impermeable to water and permeable to electrolytes.

So, the correct answer is 'Thin descending loop of Henle'.
