8.5 POJA-L457. Peripheral alveolar area of the lung

​8.5  POJA-L457

Title: Peripheral  alveolar area of the lung 
 
Description: 
Stain Azan, human. (1) Part of a pulmonary artery in a septum (2). (3) represents part of a bronchiolus respiratorius that continues into several alveolar ducts (4) and subsequently in alveolar sacs. Arrows (↓) indicate small foci of carbon deposits.
 

8.5 POJA-L374. Epithelium of respiratory bronchiole

​8.5  POJA-L374

Title: Epithelium of respiratory bronchiole
 
Description:
Stain Azan, human. An irregular lining of low columnar - cuboidal cells (1) and thin alveolar epithelium (2) are present. Note cuboidal Clara cells (↓). 
At (3) small patches of smooth muscles and at (4) macrophages with phagocytized carbon particles (black dots).  Small pulmonary artery (5), lymph capillary (6),  part of alveolus (below 2).
 

8.5 POJA-L375. Epithelial lining of respiratory bronchiole in the lung

​8.5  POJA-L375

Title: Epithelial lining of respiratory bronchiole in the lung 
 
Description:
Electron microscopy, rat. The epithelial lining of the respiratory bronchiole contains ciliated cells (1) and Clara cells (2) with electron-dense secretory granules.
At (4) interstitium with elastin, collagen and myofibroblasts ; (5) shows a small pulmonary arteriole. At arrow (→) a sharp demarcation between the last Clara cell (2) and the first type I alveolar cell (pneumocyte I). White granulated cells (3) represent type II alveolar cells (pneumocytes II); (A) are alveoli.
