Alveolar macrophage. Inclusions of hemosiderin contain iron but no calcium. Lower left, Macrophage is observed on transmission electron microscope. Upper right, Thin section of macrophage is observed on scanning electron microscope. Shadow of cell is visible, and inclusions of hemosiderin have higher secondary electron emission than cell's cytoplasm. Upper left, Mapping of iron of same cell is shown by x-ray microanalysis.
