The blood from the glomerulus is carried away by:
1. Afferent arteriole
2. Efferent arteriole
3. Peritubular capillary network
4. Renal vein
Removal of proximal convoluted tubule from the nephron will result in
(1) more diluted urine
(2) more concentrated urine
(3) no change in quality and quantity of urine
(4) no urine formation
Our excretory system has
1.Two million nephrons
2.One million nephrons
3.Two million neurons
4.One million neurons
Nephron is a
1.Structural unit of the kidney
2.Functional unit of the kidney
3.Both structural and functional unit of the kidney
4.Structural unit of Neuron
Which of the following is not a part of nephron?
1.Glomerulus
2.PCT
3.Collecting Duct
4.DCT
Cortical nephron
1.Either do not have vasa recta
2.Highly reduced vasa recta
3.Both A and B
4.Dipped in the inner part of the kidney

4. | (v) | (iv) | (i) | (iii) |
1. | Henle’s loop – most reabsorption of the major substances from the glomerular filtrate |
2. | Distal convoluted tubule – reabsorption of ions into the surrounding blood capillaries |
3. | Afferent arteriole – carries the blood away from the glomerulus towards renal vein |
4. | Podocytes - create minute spaces (slit pores) for the filtration of blood into the Bowman’s capsule |
Match the following parts of a nephron with their function:
(a) | Descending limb of Henle's loop | (i) | Reabsorption of salts only |
(b) | Proximal convoluted tubule | (ii) | Reabsorption of water only |
(c) | Ascending limb of Henle's loop | (iii) | Conditional reabsorption of sodium ions |
(d) | Distal convoluted tubule | (iv) | Reabsorption of ions, water, and organic nutrients |
Select the correct option from the following:
Options: | (a) | (b) | (c) | (d) |
1. | i | iii | ii | iv |
2. | ii | iv | i | iii |
3. | i | iv | ii | iii |
4. | iv | i | iii | ii |
I: | Allows passage of small amounts of urea into the medullary interstitium |
II: | Large amounts of water could be reabsorbed from this part to produce a concentrated urine. |
1. | Only I | 2. | Only II |
3. | Both I and II | 4. | Neither I nor II |
