A large quantity of fluid is filtered everyday by nephrons in the kidney but only about of it is excreted as urine. The remaining 99% of the filtrate
1 is stored in the urinary bladder
2 is reabsorbed into the blood
3 gets collected in the renal pelvis
4 is lost as sweat.
Explanation:
(b) Acomparison of the volume of the filtrate formed per day ( 180 litres) with that of the urine released ( 1.5 litres), suggests that nearly of the filtrate is reabsorbed by the renal tubules into the blood.

Juxta-glomerular apparatus is formed by cellular modification in the
1 afferent arteriole and DCT
2 efferent arteriole and PCT
3 afferent arteriole and PCT
4 efferent arteriole and DCT
Explanation:
(a) Juxta-glomerular apparatus is a microscopic structure located between the vascular pole of the renal corpuscle and the returning distal convoluted tubule of the same nephron. It is formed by cellular modification in the afferent arteriole and DCT.

1 There will be no urine formation
2 There will be hardly any change in the quality and quantity of urine formed
3 The urine will be more concentrated
4 The urine will be more dilute
Explanation:

Identify the parts mentioned below which constitute a part of single uriniferous tubule.
i. Loop of Henle. ii. Collecting duct
iii. Bowman's capsule iv. Distal convoluted tubule
1 i, ii and iii
2 ii, iii and iv
3, iii and iv
4 All of the above
Explanation:
(c) A uriniferous tubule/nephron is a long tubule differentiated into four regions - Bowman's capsule, proximal convoluted tubule, loop of Henle and distal convoluted tubule. Collecting ducts are the larger tubes, each receiving the collecting tubules of several nephrons. It does not form a part of the uriniferous tubule.
