Why are our kidneys important? For starters, kidneys literally never take a day off. Ever. Their role is to keep your blood clean, filtering over 50 gallons of blood through 140 miles of kidney tubes every single day. Each hour, your body’s total blood supply circulates through your kidneys about 12 times. 99% of the blood is reabsorbed and redistributed while only 0.1% is filtered into urine.
