The alveoli at the end of the bronchioles of the lung become weakened and enlarged due to the breakdown of their walls. With fewer and larger sacs means a reduced surface area for the exchange of oxygen into the blood and carbon dioxide out of it. When the individual exhales, the damage alveoli won’t work properly trapping old air in lung, not allowing any room for fresh air to enter. With proper treatment, it may slow progression of the disease, but the damage can’t be reversed (Mayo 2013).
