The Urinogenital System and the Kidneys

I n large part our good health depends on the quality of the body's internal environment. There is a kind of ecological principle at work within us—if one chain threatens to break, one system becomes polluted, one balance is tilted, then the whole environment is in imminent danger of collapsing. The major responsibility for keeping our internal environment clean and unclogged lies with our two kidneys. They are the filters and purifiers of body fluids: the body's pollution-control stations, its recycling plants, and its waste-disposal units.
