The aorta sends off branches to the head, neck, viscera, and upperand lower extremities, which divide and subdivide into innumerablesmaller branches, which ramify upon the bones, muscles, skin, andevery part of the body, until they are finally lost in the little capil-lary vessels, the same as the extremities of the pulmonary arteries.Every tissue of the body is full of these capillaries, which form theconnecting link between the arteries and the veins. It is while theblood is passing through these, that its nutritive properties aretaken up and assimilated to the different parts of the body, by a stillsmaller set of vessels, which open into these, called the nutritive THE LAWS OF HEALTH. 53 capillaries. In this way the blood is made to nourish, sustain, andreplenish the system. In this way the growth of the body is effected,and all the new particles obtained to supply the continual waste thatis going on in the various tissues. Fig. 10.

An ideal view of the Circulation in the Lungs and System.1, Eight auricle; 2, right ventricle; 3, pulmonary artery; 4, 5, left and rightbranches, going to the lungs; 6, 6, the capillaries of the lungs; 7, 8, pulmonary veins,returning blood to left auricle of the heart; 9, left auricle; 19, left ventricle; 11,20, aorta; 12, 13, 13, branches of aorta, ascending and descending; 14, 14, the capil-laries, into which the arteries terminate, and from which the veins rise; 15, 16,descending and ascending vena cava. g^^The arrows show the course of the blood. Having parted with its nutritive properties, and also lost much ofits oxygen, the blood is ready to be sent back to the heart, and thenceto the lungs to be again purified and renewed. It has again becomequite dark, from the loss of its oxygen, and the presence of carbon.From the capillaries therefore it passes into the extremities of theveins, and thence is collected from all parts into larger veins, all ofwhich terminate at last in the t
