Longitudinal Section of a Primary Lobule of the Lung

Schematic of the anatomical unit (Miller.)

Legend

r. b. - respiratory bronchiole
al. d. - alveolar duct
at. - atria
a. s. - alveolar sac
a - alveolus or air cell
p. a. - pulmonary artery
p. v. - pulmonary vein
l. - lymphatic
l. n. - lymph node

The alveoli are lined by a delicate layer of simple squamous epithelium, the cells of which are united at their edges by cement substance. Between the squames are here and there smaller, polygonal, nucleated cells. Outside the epithelial lining is a little delicate connective tissue containing numerous elastic fibers and a close net-work of blood capillaries, and forming a common wall to adjacent alveoli (Fig. 975).
