| Alveolar Macrophage: |
a) A scavenger cell that thrives naturally and can engulf (phagocytize) inhaled microbes and particles deposited in the alveolar region of the lungs. These are migratory cells which constitute a major part of the natural lung microflora and resistance of the body to diseases related to bacteria, fungi and viruses. Health Note: Reduction of the alveolar macrophage population can result in infection and scarring by certain particulate matter air contaminates. Respiratory Protection Note: Proper respiratory protection by mitigation employees is their only defense in protecting the alveolar macrophage cells and reducing lung damage (scarring). |
