This anatomical illustration depicts a male figure coughing while labeled diagrams compare cross-sections of normal bronchioles and alveoli-filled with air and appearing pink-with those affected by pneumonia, where alveoli are congested with yellow fluid. Key structures like the windpipe (trachea), lungs, and bronchus are clearly labeled to aid understanding of respiratory pathology. The image emphasizes the physiological impact of infection on gas exchange.
