The image depicts the bronchial tree with magnified insets highlighting hallmark pathologies of COPD: on the left, chronic bronchitis shows thickened airway walls, excessive mucus production, and inflammatory infiltration; on the right, emphysema reveals enlarged, ruptured alveolar sacs and reduced gas exchange surface area. Both conditions lead to airflow limitation and progressive respiratory decline.
