Match the items given in column I with those in column II and select the correct option given below.

  1. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
  2. (a)-(iv), (b)-(v), (c)-(ii), (d)-(iii)
  3. (a)-(v), (b)-(iv), (c)-(i), (d)-(iii)
  4. (a)-(v), (b)-(iv), (c)-(i), (d)-(ii)

Answer

(1) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

Solution

(a) As per NCERT, glomerular filtration is an ultrafiltration that occurs in the Malpighian corpuscle (renal corpuscle = glomerulus + Bowman's capsule) ⇒ (iv)

(b) Henle's loop maintains the high osmolarity of the medullary interstitial fluid by the counter current mechanism, which helps to concentrate urine ⇒ (i)

(c) The ureters carry urine from the kidneys to the urinary bladder ⇒ (ii)

(d) The urinary bladder stores urine till micturition ⇒ (iii)

∴ (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

Answer: (1)

In mammals, which blood vessel would normally carry largest amount of urea?

  1. Hepatic Vein
  2. Hepatic Portal Vein
  3. Renal Vein
  4. Dorsal Aorta
NEET 2016 (Phase 1)

The part of nephron involved in active reabsorption of sodium is

  1. distal convoluted tubule
  2. proximal convoluted tubule
  3. Bowman's capsule
  4. descending limb of Henle's loop
NEET 2016 (Phase 2)
6

Human urine is usually acidic because

  1. potassium and sodium exchange generates acidity
  2. hydrogen ions are actively secreted into the filtrate
  3. the sodium transporter exchanges one hydrogen ion for each sodium ion, in peritubular capillaries.
  4. excreted plasma proteins are acidic

Which of the following does not favour the formation of large quantities of dilute urine?

  1. Renin
  2. Atrial natriuretic factor
  3. Alcohol
  4. Caffeine

9

Removal of proximal convoluted tubule from the nephron will result in

  1. no change in quality and quantity of urine
  2. no urine formation
  3. more diluted urine
  4. more concentrated urine.
AIPMT 2015 (Cancelled)
10

Which of the following causes an increase in sodium reabsorption in the distal convoluted tubule?

  1. Increase in aldosterone levels
  2. Increase in antidiuretic hormone levels
  3. Decrease in aldosterone levels
  4. Decrease in antidiuretic hormone levels

Figure shows human urinary system with structures labelled A to D. Select option which correctly identifies them and gives their characteristic and/or functions. [Figure]

  1. A - Adrenal gland - located at the anterior part of kidney. Secrete catecholamines which stimulate glycogen breakdown.
  2. C - Medulla - inner zone of kidney and contains complete nephrons.
  3. B - Pelvis - broad funnel shaped space inner to hilum, directly connected to loops of Henle.
  4. D - Cortex - outer part of kidney and do not contain any part of nephrons.
