alveolar cell

A nonspecific term for any cell native to the pulmonary alveoli—e.g., type-I and type-II pneumocytes and alveolar macrophages.

(al-vē'ŏ-lăr sel)
Any of the cells lining the alveoli of the lung, including the squamous alveolar cells, the great alveolar cells, and the alveolar macrophages.

alveolar cell

1. In the lung, either of two types of epithelial cells lining the alveoli. Type I cells are simple thin squamous epithelial cells. Type II cells secrete pulmonary surfactant. Type II cells are smaller and more numerous than Type I cells.
2. In the mammary glands, the milk-secreting epithelial cells, which are activated during lactation.
