In man which blood vessel takes away blood from the kidney?
-
Afferent arteriole
-
Efferent arteriole
-
Renal vein
-
Renal portal vein
C
Correct answer
Explanation
The renal vein carries deoxygenated blood away from the kidney toward the inferior vena cava. The afferent arteriole brings blood TO the glomerulus, and efferent arteriole carries blood away FROM the glomerulus (but still within kidney). Renal portal veins are found in lower vertebrates like birds and reptiles, not mammals. Renal vein is the correct answer for the vessel that 'takes away blood from the kidney.'
