All The Blood In Our Bodies Passes Through The Kidneys Several Times A Day. The Kidneys Remove Wastes, Control The Body's Fluid Balance, And Regulate The Balance Of Electrolytes. As The Kidneys Filter Blood, They Create Urine, Which Collects In The Kidneys' Pelvis -- Funnel-Shaped Structures That Drain Down Tubes Called Ureters To The Bladder.
