The nutrition, re- ceived into the blood from the digestive apparatus, as will be shown later on, replaces worn-out tissues. The oxygen of the red corpuscles is consumed in maintaining the heat of the body, and the blood flows on, taking with it the dead cells of worn-out tissues, the red corpuscles, largely deprived of their oxygen, and the white corpuscles, with their burden of absorbed germs, through the veins in a steady stream to the heart. From there it is pumped into the lungs, blue in color and exhausted of vitality, to be vitalized with oxygen and relieved of its waste matter. From the lungs it goes back to the heart again, purified and enriched, to repeat its function. As the result of repeated.
