Pulmonary emphysema
Note that the alveoli (air spaces) in this slide are much larger than in the slide of normal lung. The functional efficiency of this lung is much reduced as compared to normal.
Emphysema (40X2.0) Normal lung (40X2.0)
Destruction of tissue leaves little surface area, few Much normal tissue creates large surface area
capillaries, and large air spaces. Large vessel at lower with many capillaries, many small air spaces. Large
right vessel at extreme left, large airway at lower right
Emphysema (100X2.0) Normal lung (100X2.0)
Destruction of tissue leaves little surface area, few Much normal tissue creates large surface area
capillaries, and large air spaces with many capillaries, which are filled with
RBCs (red cells)
