How the kidneys clean your blood
Healthy kidneys work like clockwork to clean the blood. These 2 bean-shaped organs are found near the middle of the back below the rib cage. They filter about 200 quarts of blood daily. Every day, the kidneys remove about 2 quarts of water and waste products in the form of urine. The urine then moves into the kidney's collecting system, the renal pelvis. It then flows through the ureters to the bladder, where it is stored until it is pushed out of the urethra.
