Question

Match the items given in Column I with those in Column II and select the correct option given below :

Column I (Function)		Column II (Part of Excretory System)
a.	Ultrafiltration	i.	Henle’s loop
b.	Concentration of urine	ii	Ureter
c.	Transport of urine	iii.	Urinary bladder
d.	Storage of urine	iv.	Malpighian corpuscle
		v.	Proximal convoluted tubule

• A. a-iv, b-v, c-ii, d-iii
• B. a-v, b-iv, c-i, d-ii
• C. a-iv, b-i, c-ii, d-iii
• D. a-v, b-iv, c-i, d-iii

Answer 1

The Correct Option is A

Let's solve the question by matching items from Column I (Function) with those in Column II (Part of Excretory System) and find the correct options.

1. Ultrafiltration is primarily a function of the Malpighian corpuscle, which is a part of the nephron in the kidneys responsible for filtering blood plasma. This matches a-iv.
2. The Concentration of urine largely takes place in the Henle’s loop and the Proximal convoluted tubule. However, since we focus on concentration specifically within the context of this question, Proximal convoluted tubule is more closely linked to this function. This matches b-v.
3. The Transport of urine is the role of the Ureter, which carries urine from the kidneys to the urinary bladder. This matches c-ii.
4. The Storage of urine is done by the Urinary bladder, which holds the urine until it is expelled from the body. This matches d-iii.

Considering all the above matches, the correct combination is:

a-iv, b-v, c-ii, d-iii

This aligns with the functions and parts of the excretory system within the human body.
