Question

Match the following.

	List I	List II
(A)	Ascending limb of Henle's loop	(I) Concentration of glomerular filtrate is high
(B)	Proximal convoluted tubule	(II) Facultative water re-absorption
(C)	Collecting tubule	(III) Imperameable to water
(D)	Distal convoluted tubule	(IV) Obligatory water re-absorption

Identify the sequence of List II with respect to List I.

• A. A- (I), B- (IV), C- (III), D- (II)
• B. A- (III), B- (IV), C- (I), D- (II)
• C. A- (II), B- (IV), C- (III), D- (I)
• D. A- (III), B- (I), C- (II), D- (IV)

Answer 1

Answer: (B)

A- (III), B- (IV), C- (I), D- (II)

The thin ascending limb is impermeable to water but it is permeable to ions.

Proximal convoluted tubule collect reabsorb water and supply it to peritubular capillaries.

Collecting tubule is responsible in increasing the concentration of glomerular filtrate.

The main function of distal convoluted tubule is resorption of sodium, water and secretion of hydrogen potassium.

Thus, the correct answer is option B.
