Read the following statements carefully: Statement I: In juxtamedullary nephrons, the Malpighian corpuscle is located deep inside the renal medulla. Statement II: Cortical nephrons constitute the majority of the total nephrons in the human kidney. Statement III: Vasa recta is highly reduced or absent in cortical nephrons. Statement IV: The efferent arteriole emerging from the glomerulus forms a fine capillary network

Step-by-step solution

Statement I is incorrect because the Malpighian corpuscle, PCT and DCT of all nephrons (including juxtamedullary nephrons) are situated in the cortical region of the kidney. Statement II is correct as cortical nephrons form the majority of the nephrons, while juxtamedullary nephrons are fewer in number. Statement III is correct because the vasa recta is highly reduced or absent in cortical nephrons, whereas it is well developed in juxtamedullary nephrons. Statement IV is correct as the efferent arteriole emerging f
