| 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 |
