Question

Peritubular capillaries develop from

• A. Renal vein
• B. Afferent arteriole
• C. Efferent arteriole
• D. Arcuate artery

Answer 1

The correct option is C Efferent arteriole

The blood reaches the glomerulus through afferent arteriole and the blood vessel moving away from glomerulus is efferent arteriole. The efferent arteriole emerging from the glomerulus forms a fine capillary network around the renal tubule called the peritubular capillaries. Hence peritubular capillaries develop from efferent arteriole.

So, the correct answer is 'Efferent arteriole'.
