The lighter-colored disks in the vessels and in the connecting tis- sues are white corpuscles; the darker ones are red corpuscles. Ordinarily, the red corpuscles float in the cen- ter of the cur- rent, while the white ones, due to a certain voli- tion of their own, float along near the walls of the capillaries. 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 corpus- cles 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, 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 vital- ized 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 experiments, it has been esti- mated that it takes, in the horse, thirty-one seconds for the blood to complete this round of circulation. If the flow of the blood in the capillaries, for any reason, is impeded, the white corpuscles pass through the walls of those ves- sels and accumulate in the neighboring tissues.
