Understanding COPD: Chronic Bronchitis vs. Emphysema Explained #3075997 (License: Personal Use)

The image illustrates the anatomical changes in Chronic Obstructive Pulmonary Disease (COPD), highlighting two key subtypes: chronic bronchitis, where airways become inflamed and filled with excess mucus, narrowing the lumen; and emphysema, where alveolar walls break down, reducing surface area for gas exchange and causing loss of lung elasticity. Both conditions lead to progressive airflow limitation and respiratory distress.

Used on medical education, pulmonology, or patient resource pages to visually explain COPD pathophysiology; targets users seeking to understand symptoms, diagnosis, or treatment options for COPD.
