Let us learn what are the many inti-mate relations of the blood pump and the air pump, the bloodsystem and the air system, of Circulation and Respiration. The Organs ofRespiration are; — 1. The Lungs andAir Tubes. 2. The structureswhich increase and di-minish the size of thechest, principallythe diaphragm, andthe muscles actingon the ribs. The lungs con-sist of: — 1. An immensenumber of small sacs, the Air Ves-icles, which com-municate with theouter air by the Bronchial Twigs, Bronchi, and Trachea. 2. The Pulmonary Capillaries, forming a thick network 105.

These capillaries receivetheir blood from the pulmonary artery, and return it to theheart by the pulmonary veins.
