Question

Vasa recta is absent or highly reduced in–

• A. Cortical nephrons
• B. Juxta medullary nephrons
• C. Peritubular capillaries
• D. Both $\left(1\right)$ and $\left(2\right)$

Answer 1

The correct option is A Cortical nephrons

Vasa recta is absent or highly reduced in cortical nephrons because cortical nephrons are mainly concerned with the concentration of urine. So, they have short loop of Henle and no vasa recta.
Therefore, the correct answer is 'cortical nephron'.
