            The heart is a combination consisting of two different pumps. The one on the left
            pumps oxygenated blood to the body’s organs and tissues, and the one on the
            right pumps CO -laden blood to the lungs, causing all the blood in the body to cir-
                         2
            culate 1,000 times a day. An adult heart pumps 250 million liters (66,040,000 gal-
            lons) of blood over a 70-year life span. (“The Incredible Machine,” National
            Geographic Magazine, Washington D.C., 1986, p. 123)



            and replaced with oxygen. The left-hand chambers pos-
            sess thicker muscles, since they pump at a higher pres-
            sure in order to send blood to reach the whole body. The
            heart’s most important feature is how it works
            non-stop, beating approximately 70 times a
            minute, 100,000 times a day, and 40 million times
            a year. During the course of an average lifetime, it beats
                   47
            more than 2 billion times and pumps enough blood to fill an
            average of 100 swimming pools.
                 Also exceedingly important is that the heart’s inde-
            fatigable muscles pump a level of blood that depends on
            the prevailing circumstances. During sleep, the heart pumps
            approximately 340 liters (90 gallons) of blood an hour, while
            during physical activity,—for instance, when running—it
