Healthy vs. Diseased Lung Anatomy - Medical Illustration #167381 (License: Personal Use)

This black-and-white medical illustration contrasts two human lungs side by side: the left displays a normal pulmonary structure with well-defined bronchi and alveolar pathways, while the right exhibits pathological changes such as irregular, clustered airspaces or fibrotic scarring-common in conditions like idiopathic pulmonary fibrosis or advanced emphysema. The central trachea and vertebral column provide anatomical orientation, emphasizing structural deviation from health. The image serves as an educational tool to highlight how disease alters lung morphology and function.

Used in healthcare websites, patient education portals, medical textbooks, and pulmonology resources to explain respiratory diseases like COPD, pulmonary fibrosis, or cystic lung disorders; matches user intent seeking visual understanding of lung pathology or symptom causes.
