Match the items given in Column I (Function) with those in Column II (Part of Excretory system) and select the correct option given below:
Column I
a. Ultrafiltration
b. Concentration of urine
c. Transport of urine
d. Storage of urine
Column II
i. Henle's loop
ii. Ureter
iii. Urinary bladder
iv. Malpighian corpuscle
v. Proximal convoluted tubule
Correct answer: a → iv, b → i, c → ii, d → iii
Solution
Filtration in Malpighian corpuscle, concentration in Henle's loop, transport by ureter, storage in bladder.
Ultrafiltration refers to filtration of very fine particles having molecular weight less than 68,000 daltons through the Malpighian corpuscle.
Concentration of urine refers to water absorption from glomerular filtrate as a result of hyperosmolarity in the medulla created by the counter-current mechanism in Henle's loop.
Urine is carried from the kidney to the bladder through the ureter.
The urinary bladder is concerned with storage of urine.
Correct match: a-iv, b-i, c-ii, d-iii.
