| I: | Glomerulus is a tuft of capillaries formed by the efferent arteriole |
| II: | Afferent arteriole forms the peritubular capillary network |
| III: | Vasa recta is absent or highly reduced in juxtamedullary nephrons |
| 1. | Only III is correct |
| 2. | I is correct but II and III are incorrect |
| 3. | I, II and III are incorrect |
| 4. | I and II are correct |
| 1. | glomerulus is a tuft of capillaries formed by the efferent arteriole |
| 2. | vasa recta is highly reduced in juxtamedullary nephrons |
| 3. | DCTs of many nephrons open into a straight tube called collecting duct |
| 4. | columns of Bertini are extensions of medulla into the cortex |
| 1. | Glomerulus is a tuft of capillaries formed by afferent arteriole. |
| 2. | Blood from the glomerulus is carried away by an efferent arteriole. |
| 3. | Vasa recta is well developed in cortical nephrons. |
| 4. | The DCTs of many nephrons open into a straight tube called collecting duct. |
| I: | is lined by cuboidal brush bordered epithelium |
| II: | reabsorbs 70-80 percent of electrolytes and water |
| 1. | Proximal convoluted tubule |
| 2. | Loop of Henle |
| 3. | Distal convoluted tubule |
| 4. | Collecting duct |
