1. | pelvis; calyces | 2. | medulla; pyramids |
3. | cortex; columns of Bertini | 4. | cortex; lobes |
Malpighian body or the renal corpuscle is made up of:

2. Bowman's capsule and renal tubules
3. Afferent and efferent arterioles
4. Glomerular capillaries and Bowman's capsule
I: | Each kidney of an adult human measures 10-12 cm in length, 5-7 cm in width and 2-3 cm in thickness. |
II: | The DCTs of many nephrons open into a straight tube called collecting duct. |
III: | Each nephron has two parts – the glomerulus and the renal tubule. |
IV: | The renal tubule begins with the proximal convoluted tubule. |
1. | Only I and II | 2. | Only I, II and III |
3. | Only II and III | 4. | I, II, III and IV |
I: | is a fine capillary network around the renal tubule formed by efferent arteriole. |
II: | runs parallel to the Henle’s loop in juxtamedullary nephrons. |
III: | is absent or highly reduced in cortical nephrons. |
