Chronic obstructive pulmonary lung disease (COPD) is a lung disease in which the lungs are damaged, making it hard to breathe. In COPD, the airways- the tubes that carry air in and out of your lungs are partly obstructed, making it difficult to get air in and out. The airways branch out like an upside-down tree, and at the end of each branch are many small, balloon-like air sacs called alveoli (al-VEE-uhl-EYE).
