The greatest advance of modern times in the understanding of circulatory disease is due to the better knowledge of the functions of the heart and peripheral circulation. So long as the heart was considered the only active organ, and the blood vessels were regarded as passive tubes through which the blood circulated, it was not possible to believe in the cure of diseases of the circulation, except in so far as the heart itself could be repaired. The modern observer sees the origin of most heart disease outside of the heart itself, and discovers a hopeful field for relief in the indirect effect upon the heart of a proper regulation of its burdens in the general circulation. When Harvey discovered the circulation of the blood and demonstrated the beautiful picture of the heart pumping the blood through the blood vessels, it made such an impression upon the world that for many years, indeed, now for centuries, superficial observers have been chiefly occupied in admiring the picture, and enough practical thought has not been given as to why the blood circulates as it does. The point that has been slowest to be appreciated is that the blood is circulating through living tubes, and not through a series of inanimate pipes. The function of these tubes is so dependent upon life that, when life is destroyed, they become, absolutely incapable of carrying on the circulation.
