8.5 POJA-L393. Alveolar macrophage in lung

​8.5 POJA-L393

Title: Alveolar macrophage in lung 
 
Description:
Electron microscopy, rat.  A wandering alveolar macrophage (1) migrates through an alveolar pore from an alveolar space (A1) into another one (A2). Note the dark lysosomal structures and abundant organelles in its cytoplasm. The thin lining type I alveolar cell is hardly discernable (thin arrows →, zoom in).  Interstitial cells are marked with (**). Capillaries (2) are indicated with erythrocytes or platelets.
 

8.5 POJA-L394. Alveolar macrophages in lung

​8.5  POJA-L394

Title: Alveolar macrophages in lung 
 
Description:
Electron microscopy, adult human. Two macrophages in the alveolar space. (N= nucleus).  Note the heterogeneity of many lysosomal structures containing among others carbon particles and the abundancy of organelles.
