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 gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD).Smoking is the leading cause of emphysema.Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture â creating one larger air space instead of many small ones.This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream.our lungs' alveoli are clustered like bunches of grapes.
