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

The Correct Option is B

Evaluating Statements about Nephron Function:

• Statement I: The descending limb of the loop of Henle is permeable to water but impermeable to electrolytes. 
  Evaluation: This statement is false.
• Statement II: The proximal convoluted tubule is lined by columnar epithelium, increasing surface area for reabsorption through microvilli. 
  Evaluation: This statement is false (it is lined by cuboidal epithelium).

Thus, the correct answer is (2) Both Statement I and Statement II are false.
