Questions:

  1. What are the different types of respiration (cellular, internal, and external)? Where does each occur?
  2. What is pulmonary ventilation?
  3. What functions does the nose perform? What structures perform/contribute to these functions?
  4. What is the olfactory mucosa?
  5. What is the function of the trachea? Why aren't the tracheal C-rings O-rings?
  6. How does the respiratory system protect itself from infection (hint: there are multiple ways)?
  7. Briefly describe the anatomy of the conductive and respiratory divisions of the respiratory system.
  8. Describe the function of the different alveolar cells. Why is each important in maintaining lung function?
  9. What is the respiratory membrane? What are its components? What characteristics of the respiratory membrane influence its function?
  10. What muscles aid in inspiration, deep inspiration, and forced expiration? Be specific.
  11. How do the pleural membranes help in inhalation and exhalation? What other functions do these membranes serve?
  12. Describe the pressure changes in the alveoli and atmosphere that occur during inspiration. What volume changes cause these pressure changes?
  13. Describe the pressure changes in the alveoli and atmosphere that occur during expiration. What volume changes cause these pressure changes?
  14. Compare the relative pressures in the alveoli and atmosphere at the end of inspiration or expiration.
  15. Describe the various non-respiratory air movements.
  16. Describe the following lung volumes: IRV, ERV, TV, and RV. What factors could affect the volumes?
  17. Describe the following lung capacities: TLC, VC, IC, EC, and FRC.
  18. Be able to interpret hemoglobin dissociation curves. How does P02 influence O2 and CO2 loading and unloading?
  19. What happens to the ability of Hb to give up O2 during exercise (increased temperature, increased CO2, decreased O2)? Why? How does the graph change?
  20. What is the significance of the CO2 + H2O → HCO3- + H+ reaction? How does it influence the respiratory rate?
  21. What inputs control ventilation? How does altered blood chemistry change ventilation rates?
  22. What part of the brain controls ventilation?
  23. Describe the signs, symptoms, causes, and risk groups for each of the respiratory disorders discussed in class.
