Question

The afferent and efferent vessels are

• A. Arterial in nature
• B. Venous in nature
• C. One is arterial and the other is venous
• D. None of the above

Answer 1

The correct option is A Arterial in nature

The afferent vessel and efferent arteriole is arterial in nature. The renal artery enters the kidney and breaks into several arteriole. The arteriole enters the glomerulus as afferent arteriole and supplies oxygenated, urea loaded blood to the glomerulus. The blood is filtered out by ultrafiltration and the deoxygenated blood leaves the glomerulus as efferent arteriole. The efferent arteriole further breaks into capillaries and forms vasa recta which further joins to form the renal vein.

The correct answer is option 'A'.
