1. | Renal corpuscle of juxta medullary nephron lies in the outer portion of the renal medulla. |
2. | Loop of Henle of juxta medullary nephron runs deep into medulla. |
3. | Juxta medullary nephrons outnumber the cortical nephrons. |
4. | Juxta medullary nephrons are located in the columns of Bertini. |
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 |
Which of the following statements is correct?
1. | The descending limb of loop of Henle is impermeable to water. |
2. | The ascending limb of loop of Henle is permeable to water. |
3. | The descending limb of loop of Henle is permeable to electrolytes. |
4. | The ascending limb of loop of Henle is impermeable to water. |
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 |
