Question

Given below are two statements :
Statement I : In the nephron, the descending limb of loop of Henle is impermeable to water and permeable to electrolytes.
Statement II : The proximal convoluted tubule is lined by simple columnar brush border epithelium and increases the surface area for reabsorption.
In the light of the above statements, choose the correct answer from the option given below :

• A. Both statement I and Statement II are true
• B. Both statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Answer 1

Answer: (B)

Both statement I and Statement II are false

Answer 2

- Statement I is false. The descending limb of the loop of Henle is permeable to water but impermeable to electrolytes.

- Statement II is false. The proximal convo luted tubule is lined by simple cuboidal epithelium with a brush border, not columnar epithelium. The brush border increases the surface area for absorption.

Thus, both statements are false, so the correct answer is (1).
