                 CELLS THAT PRODUCE THEIR OWN ENERGY

                 As you have already seen, your body functions with electricity.
            However, in contrast to the other electrical systems we are accustomed
            to seeing, your body takes in no electricity from the outside.
                 Consider any electrical device. In order for it to
            function, it requires an electrical current provided
            from some outside source, or else to be by means of
            batteries. Otherwise, in the absence of electrical en-
            ergy, even the most advanced machine will serve no
            purpose. But in contrast your body creates the very
            energy it needs. Trillions of cells produce—and
            use—electricity in order for life to continue.
                 Every cell is like a miniaturized battery that per-
            mits the body to function as a whole. Surrounding the
            cell is a liquid rich in potassium, and the inside is full
            of liquid high in sodium. When you mix potassium and
            sodium, the two chemicals react and an electricity
            emerges as a side product. This is analogous to
            a car battery’s producing electricity when
            sulfuric acid and lead come in contact. In
            much the same way that radios, music
            players, flashlights, clocks and appli-
            ances work with energy they obtain from
            batteries, no car can operate without
            the energy stored in its battery.
