Human Respiratory System Diagram - Healthy vs. Diseased Lung Comparison #236282 (License: Personal Use)

This anatomical illustration depicts the human upper torso with the trachea, bronchi, and both lungs clearly labeled. The left lung is shaded red to indicate inflammation, infection (e.g., pneumonia), or pathology such as pulmonary edema or tumor involvement, while the right lung remains white to represent normal, healthy tissue. The image emphasizes structural differences in vascularization and airway patency associated with respiratory illness.

Used in medical education, telehealth platforms, patient brochures, and clinical websites to explain lung conditions like pneumonia, COPD, or lung cancer; supports user intent to understand symptoms, diagnoses, or treatment options.
