Question

8. Match excretory functions in column I with the parts of the excretory system in column II and choose the correct option from the codes given below.

Column 1	Column 2
Ultrafiltration	Henle's loop
Concentration	Ureter
Transport of urine	Urinary bladder
Storage of urine	Malpighian corpuscle

Answer 1

(A) Ultrafilration- (iv) malpigihian corpuscle

1. Ultrafiltration refers to the filtration of very fine particles having a molecular weight of fewer than 68,000 daltons through the malpighian corpuscle.

(B) concentration (i) Henle's loop.

1. The 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.

(C)Transport of Urine (ii) ureter

1. Urine is carried from kidney to bladder through the ureter.

(D) Storage of urine (iii) The urinary bladder

1. The urinary bladder is concerned with the storage of urine

column I	column II
A. ultrafiltration	(iv) malpighian corpuscle.
B. concentration	(i) Henle's loop.
C. Transport of urine	(ii) ureter
D. Storage of urine	(iii) The urinary bladder
