Handbook of anatomy; being a complete compend of anatomy, including the anatomy of the viscera a chapter on dental anatomy, numerous tables, and incorporating the newer nomenclature adopted by the German anatomical Society, generally designated the Basle nomenclature or BNA . bule represents the structure of the entire organ, con-sisting of a bronchiole (bronchioli) and infundibula, or air-passage, communicating with numerous air-cells. The air-cells (infundibula) are minute polyhedral cavities,from one-two-hundredths to one-seventieth of an inch in diam-eter, separated from each other by a thin lamina, and communi-cating freely with the infundibula. They vary much in size,being largest on the surface at the thin borders and at the apices. VOCAL AND RESPIRATORY APPARATUS. 263 Bach air-cell is composed of the basemenl membrane, lined withsquamous epithelium, and surrounded by a minute capillarynetwork of blood vessels, which intervene between the terminalbranches of the pulmonary artery and the commencement of thepulmonary veins. Between the cells the capillary network formsa single layer. The pulmonary artery conveys the venous blood 1 thelungs and terminates in the capillary network about the air-cells, from which proceeds the pulmonary vein, which passes. Fio. 95.
