Healthy kidneys process about 200 quarts of blood daily, about 800 cups, with an average of about half a cup a minute. After blood flows through the renal artery and enters the Bowman capsule, it passes through fifty different capillaries. It then passes through about four tubules before heading for the bladder. On average, the body excretes about two quarts of urine, or eight cups.
