Alveolar Macrophage

Phagocytic immune cells found in the alveoli of the lungs, acting as the primary defense against inhaled pathogens and particles.

Key Functions:

• Phagocytoses inhaled dust, pathogens, and debris.
• Clears the alveolar surface.
• Presents antigens and secretes cytokines.
• Crucial for lung immunity.

Interacting Systems & Components:

• Macrophage (type of)
• Alveoli (located in)
• Lung (component of)
• Immune System (key defense in respiratory tract)
• Respiratory System (protects)
