Healthy vs. Diseased Lungs: Medical Illustration for Respiratory Health Education #311950 (License: Personal Use)

The illustration contrasts two human thoracic profiles: the left depicts normal lung anatomy with fully expanded bronchial trees and well-defined alveoli, while the right shows pathological changes including constricted airways, loss of distal branching, and signs of inflammation or fibrosis. These visual differences highlight common manifestations of respiratory conditions such as asthma, COPD, or bronchiectasis. The line-drawing style emphasizes structural clarity for educational use.

Used in medical websites, patient brochures, telehealth platforms, and public health campaigns to explain lung diseases, treatment outcomes, or smoking cessation effects; matches user intent for understanding symptoms, diagnosis, or prevention of respiratory illness.
