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 o f 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. $a \rightarrow v, b \rightarrow iv, c \rightarrow i, d \rightarrow iii$
• B. $a \rightarrow iv, b \rightarrow v, c \rightarrow ii, d \rightarrow iii$
• C. $a \rightarrow v, b \rightarrow iv, c \rightarrow i, d \rightarrow ii$
• D. $a \rightarrow iv, b \rightarrow i, c \rightarrow ii, d \rightarrow iii$

Answer 1

Answer: (D)

Ultrafiltration refers to filtration of very fine particles having molecular weight less than $68,000$ daltons through malpighian corpuscle.
Concentration of urine refers to water absorption from glomerular filtrate as a result of hyperosmolarity in the medulla created by counter-current mechanism in Henle's loop.
Urine is carried from kidney to bladder through ureter.
Urinary bladder is concerned with storage of urine.
