The correct option is B False
Nitrogenous waste generated during metabolism has to be removed from our body. This is done by the excretory system. Kidney filters the blood to remove these wastes. Blood with a lot of nitrogenous waste enters the kidney through renal artery. This blood after filteration leaves the kidney through renal vein. So, the blood in renal vein has less nitrogenous waste than the blood in renal artery.
