This is normal lung microscopically. The alveolar walls are thin and delicate the alveoli are well-aerated and contain only an occasional pulmonary macrophage(type lI pneumonocyte)

Microscopically at high magnification, the loss of alveolar walls with emphysema is demonstrated. Remaining airspaces are dilated

sony styie The chest cavity is opened at autopsy to reveal numerous large bullae apparent on the surface of the lungs in a patient dying with emphysema. Bullae are large dilated airspaces that bulge out from beneath the pleura Emphysema is characterized by a loss of lung parenchyma by destruction of alveoli so that there is permanent dilation of alr spaces
