How does COPD impact the lungs?
COPD's effect on breathing. In COPD, the airways of the lungs (bronchial tubes) become inflamed and narrowed. They tend to collapse when you breathe out and can become clogged with mucus. This reduces airflow through the bronchial tubes, a condition called airway obstruction, making it difficult to move air in and out of the lungs.

A normal human lung is pink and spongy, filled with an intricate system of airways and thousands of tiny alveoli sacs.
Why do people with emphysema have a severely diminished ability to breathe?
People with emphysema have a severely diminished ability to breathe because the alveoli in their lungs have become damaged. 4. Alveoli are very tiny air pockets or sacs that are at the ends of the airways in our lungs. Alveoli sacs take oxygen from the air we breathe in and pass it through to the bloodstream.
How does carbon dioxide exit the air?
Carbon dioxide exits via the alveoli when we exhale. Over time, the toxins in cigarette smoke break down the walls between these tiny air pockets, creating bigger air sacs instead (as shown in the illustration). This is detrimental to breathing because bigger sacs mean less surface area for the gas/blood exchange.
Why do people with emphysema have shortness of breath?
The lungs become "floppier" and less spongy. 6 The airways become more likely to collapse on themselves, which is why people with emphysema will often experience shortness of breath—they aren't able to blow air back out through the lungs.
