APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Vasa recta is a network of blood vessels that surround the Loop of Henle in the medulla of the kidney. They are present in the juxtamedullary nephrons only. The function of vasa recta is to maintain the osmotic gradient in the Loop of Henle for efficient reabsorption of water.

Detailed explanation-2: -Juxtamedullary, or long-loop, nephrons have long loops of Henle that extend deep into the inner medulla. Midcortical nephrons, which have glomeruli located near the midregion of the cortex, may have long or short loops.

Detailed explanation-3: -Vasa Recta Function Not only do the vasa recta bring nutrients and oxygen to the medullary nephron segments but, more importantly, they also remove the water and solute that is continuously added to the medullary interstitium by these nephron segments.

Detailed explanation-4: -Therefore, the correct answer is ‘cortical nephron’.
