• Respiratory volumes and capacities — TV, IRV, ERV, RV, VC, FRC, and TLC with numerical-based questions
• Exchange of gases — partial pressure gradients and diffusion across the alveolar membrane
• Transport of oxygen and carbon dioxide — oxygen dissociation curve, Bohr effect, and chloride shift
• Regulation of respiration — respiratory rhythm centre, pneumotaxic centre, and chemosensitive areas
• Respiratory disorders — asthma, emphysema, bronchitis, and occupational lung diseases
