How does COPD affect the lungs?

ANSWER

COPD is an umbrella term that includes chronic bronchitis and emphysema. It usually develops in people who’ve smoked for a long time. Most people with COPD have some symptoms of both chronic bronchitis and emphysema. Bronchitis refers to inflammation in the bronchial tubes in the lungs. Emphysema happens when the tiny air sacs in the lungs, called alveoli, get destroyed. Air can get trapped in the damaged tissue. As a result, not enough oxygen makes it from the lungs into the bloodstream.
