Human Lung Inter-alveolar Septum

Type I (AEC1) and type II (AEC2) alveolar epithelial cell.

Lamellar bodies (LB) contain surfactant in type II cell.

Tight junctions (arrowheads) between type II cell and neighbouring type I cell extensions.

Collagen fibrils (col) are present in the interstitium (extracellular space).

Alv alveolar lumen, Cap capillary lumen, Endo capillary endothelial cell.

Transmission electron microscopy. Scale bar 2 µm
