Round, granular, mononuclear Phagocytes found in the alveoli of the Lungs. They ingest small inhaled particles resulting in degradation and presentation of the Antigen to immunocompetent Cells.

A type of cell that is involved in lung defenses.

Macrophage found in lung and that can be obtained by lung lavage, responsible for clearance of inhaled particles and lung surfactant. Metabolism slightly different from peritoneal macrophages (more oxidative metabolism), often have multivesicular bodies that may represent residual undigested lung surfactant.
