Question

How would you distinguish between a renal artery and renal vein in a dissected kidney?

Note:
The healthy kidneys filter about a half cup of blood every moment, eliminating wastes and additional water to make urine. Our blood circulates through our kidneys frequently. In a single day, our kidneys filter around 150 quarts of blood. Most of the water and other substances that filter through our glomeruli are returned to your blood by the tubules. Only 1 to 2 quarts become urine.
