An adult human excretes,on average,... liters of urine per day. On an average,... of urea is excreted out per day.

Match the excretory functions of Section $I$ with the parts of the excretory system in Section $II$. Choose the correct combinations from among the answers given:

Section $I$	Section $II$
$(i)$ Ultrafiltration	$(a)$ Henle's loop
$(ii)$ Concentration of urine	$(b)$ Ureter
$(iii)$ Transport of urine	$(c)$ Urinary bladder
$(iv)$ Storage of urine	$(d)$ Malpighian corpuscles
	$(e)$ Proximal convoluted tubules

$A$: Pregnant women may show some presence of glucose in their post-prandial urine although they have no diabetes.
$R$: In pregnant women,the glomerular filtration rate $(GFR)$ is slightly increased. As a result,the tubular load of glucose exceeds the tubular maximum for glucose reabsorption.

Match the following columns:

Column-$I$	Column-$II$
$a.$ Loop of Henle	$1.$ Carries blood to the kidney
$b.$ Renal artery	$2.$ Region where maximum reabsorption occurs
$c.$ Proximal Convoluted Tubule $(PCT)$	$3.$ Main site of secretion
$d.$ Glomerulus	$4.$ Filtration of blood
$e.$ Distal Convoluted Tubule $(DCT)$	$5.$ Plays a significant role in urine concentration

The correct sequence is:

The primary function of the kidney is ........ .

Match the items of column $I$ with those of column $II$:

Column $I$	Column $II$
$(a)$ Ammonotelism	$(i)$ Birds
$(b)$ Bowman's capsule	$(ii)$ Water reabsorption
$(c)$ Micturition	$(iii)$ Bony fish
$(d)$ Uricotelism	$(iv)$ Urinary bladder
$(e)$ $ADH$	$(v)$ Renal tubule
