Section role: supports the formalization of respiratory anatomy and gas exchange during Section 3 while the teacher traces the pathway of air and connects back to the diagnostic lab patients. Slides: (1) Title — 'Mapping the Airway'; (2) Pathway of Air — bullets: nasal cavity, pharynx, larynx, and trachea; (3) Lower Airways — bullets: bronchi and bronchioles branching into the lungs; (4) Alveoli and Gas Exchange — diagram of oxygen diffusion into pulmonary vessels and carbon dioxide removal, connecting to the pneumonia case from Section 2; (5) Healthy vs. Damaged Lung Tissue — comparative visual of normal tissue versus tissue affected by smoking and vaping; (6) Protecting Our Lungs — bullets: impact of urban pollution, second-hand smoke, and the benefits of regular exercise; (7) Closing slide — 'How does maintaining healthy alveoli affect your entire body's energy levels?' — sets up the individual health check in Section 4.
