Question

Match List I with List II

List I (Structure related to haemodialysis)	List II (feature)
(A). Cellophane tube	(I). Added to blood in cellophane tube
(B). Dialyzate	(II). Acts as semipermeable membrane
(C). Heparin	(III). Isosmotic to normal blood plasma
(D). Anti-heparin	(IV). Added to filtered blood returning to the vein

Choose the correct answer from the options given below:

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

Hint:

Cellophane tube is a semipermeable membrane and heparin is added to the blood before it enters the tube.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
In haemodialysis, blood from an artery passes through a coiled cellophane tube surrounded by dialysing fluid and returns to a vein.

Step 2: Match A and B
(A) Cellophane tube acts as a semipermeable membrane, so (A) goes with (II).
(B) Dialyzate is isosmotic to normal plasma but has no nitrogenous wastes, so (B) goes with (III).

Step 3: Match C and D
(C) Heparin is added to the blood before it enters the tube to prevent clotting, so (C) goes with (I).
(D) Anti-heparin is added to the cleaned blood returning to the vein, so (D) goes with (IV).

Final Answer:
The correct matching is (A) - (II), (B) - (III), (C) - (I), (D) - (IV). \[ \boxed{\text{(B) }\text{(A) - (II), (B) - (III), (C) - (I), (D) - (IV)}} \]
