alveolar macrophage

(redirected from coniophage)

al·ve·o·lar mac·ro·phage

a vigorously phagocytic macrophage on the epithelial surface of lung alveoli where it ingests inhaled particulate matter.
Synonym(s): coniophage, dust cell

alveolar macrophage

a cell of the reticuloendothelial system in the lungs that engulfs and digests foreign substances inhaled into the alveoli.

alveolar macrophage

A free mononuclear cell of the lower respiratory tract, which has a high phagocytic capacity and is responsible for clearing inhaled particles and lung surfactant. Alveolar macrophages (AMss,  are transiently attached by pseudopodia to the surface of alveolar epithelium. Presence of AMs in sputum submitted for cytologic evaluation are markers of specimen adequacy. AMs are generally submerged in a film of phospholipids, and thus form part of the surface lining of the aveoli.
