Alveolar Macrophages

Alveolar macrophages are specialized white blood cells found in the airspaces of the lungs. They play an important role in the lungs' defense against infection, by engulfing and destroying particles and pathogens which have entered the lungs. They are also involved in maintaining the health of the lungs, by removing dust particles and cellular debris from the airways and preventing their accumulation. Alveolar macrophages are important for the proper functioning of the lungs, and are essential for maintaining a healthy respiratory system.
