What is not a characteristic of the cortical nephrons?

Their nephron loop is closely wrapped with vasa recta.

Explanation:

Cortical nephrons are located in the cortex.

They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.
