Emphysema damages the tiny air sacs in the lungs, which inflate when we take in a breath and move oxygen into the blood. They also push out carbon dioxide, a waste gas, when we breathe out. When you have emphysema, these delicate air sacs can't expand and contract properly.
Emphysema caused by smoking most often occurs in the upper lobes of the lungs. In chronic bronchitis, smoking triggers inflammation that causes damage in the airways. The processes involved include: 1  Damage to the cilia, the hair-like waving projections that move mucus, bacteria, and foreign particles out of the lungs. 2  Enlargement of the mucus glands in the large airways of the lungs. 3  Overgrowth of smooth muscle cells in the airway.
