  2. Respiratory System

  3. Human Respiratory System Figure 10.1

  4. Components of the Upper Respiratory Tract Figure 10.2

  5. Upper Respiratory Tract Functions • Passageway for respiration • Receptors for smell • Filters incoming air to filter larger foreign material • Moistens and warms incoming air • Resonating chambers for voice

  6. Components of the Lower Respiratory Tract

  7. Functions of Lower Respiratory Tract • Functions: • Larynx: maintains an open airway, routes food and air appropriately, assists in sound production • Trachea: transports air to and from lungs • Bronchi: branch into lungs • Lungs: transport air to alveoli for gas exchange

  8. Gas Exchange Between the Blood and Alveoli

  9. Respiratory Cycle

  10. Measurement of Lung Capacity

  11. Regulation of Breathing

  12. Regulation of Breathing: Nervous System Involvement • Carotid and aortic bodies: sensitive to carbon dioxide, pH, and oxygen levels • Conscious control: resides in higher brain centers; ability to modify breath is limited

  13. Disorders of Respiratory System • Reduced air flow: asthma, emphysema, bronchitis • Infections: pneumonia, tuberculosis, botulism • Lung cancer • Congestive heart failure • Cystic fibrosis

  14. Process of Breathing: Pressure Gradient • Inspiration/Expiration: air in/air out • Cycle: • Relaxed state: diaphragm and intercostals muscles relaxed • Inspiration: diaphragm contracts, pulling muscle down, intercostals muscles contract elevating chest wall and expanding volume of chest, lowering pressure in lungs, pulling in air • Expiration: muscles relax, diaphragm resumes dome shape, intercostals muscles allow chest to lower resulting in increase of pressure in chest and expulsion of air

  15. Measurement of Lung Function • Lung volumes and vital capacity • Tidal volume: volume of air inhaled and exhaled in a single breath • Dead space volume: the air that remains in the airways and does not participate in gas exchange • Vital capacity: the maximal volume that can be exhaled after maximal inhalation • Inspiratory reserve volume: the amount of air that can be inhaled beyond the tidal volume
