        Urine process happens
        
        blood enters kidneys through renal artery ( - capillaries)
        
        blood pressure forces some of the water & dissolved substances in blood to cross capillary walls - bowman's capsule
        
        fluid - collecting duct
        
        filtered substances - renal tubule (nephron
