- Chronic Obstructive Pulmonary Disease (COPD): Characterized by the destruction of alveolar walls (emphysema) and chronic bronchitis, leading to impaired gas exchange. - Pulmonary Fibrosis: Involves the thickening and scarring of interstitial tissue, reducing lung elasticity and function. - Asthma: Involves inflammation and narrowing of the bronchi, leading to reduced airflow and difficulty breathing. - Lung Cancer: Can arise from various cell types within lung tissue, with adenocarcinoma being a common type originating from glandular cells.
