The blood-vessels and lymphatics.— The branches of the pulmonary artery and veins are contained within the connective tissue separat- ing the lobes and lobules, whence they can be traced into their finer ramifications towards the in- fundibula and air-cells. Each of these latter is surrounded by a sort of basket - shaped dense network of capillary blood - vessels (Fig. 129). The capillary net- works of adja- cent alveoli are continuous with one another, and stand in communication on the one hand with a branch of the pulmonary artery, and on the other with branches of the pulmonary vein. The branches of the bronchial artery belong to the. Fig; 129.—Networks of Capillary Blood-vessels surrounding the Alveoli of the Human Luns?. (Kolliker.).
