Which is true about the difference between cortical and juxtamedullary nephrons?

1. Most nephrons are juxtamedullary.
2. The efferent arteriole's of cortical nephrons give rise to most of the vasa recta
3. The aaferent arterioles of the juxtamedullary nephrons give rise to most of the vasa recta
4. Juxtamedullary nephrons generate a hyperosmotic medullary interstitium

Correct answer: The aaferent arterioles of the juxtamedullary nephrons give rise to most of the vasa recta

Solution

Juxtamedullary nephrons have long loops of Henle and are associated with the vasa recta, which arise from their efferent arterioles. This arrangement helps maintain the medullary osmotic gradient needed to concentrate urine.
