  1. This is the space inside the chest wher air flows
    airways
  2. This process is gas exchange in the lungs
    external respiration
  3. This process is gas exchange between blood and tissue
    Internal respiration
  4. This proces is taking glucose and using oxidative hosphorylation to make ATP
    cellular respiration
  5. This occurs when there is high pressure outside and low pressure inside the lungs
    Inspiration
  6. This occurs when there is low pressure outside and high pressure inside the lungs.
    expiration
  7. What does the diaphragm do during inspiration?
    contracts
  8. What are the 4 ways of breathing
    • quiet inspiration
    • quiet expiration
    • forced inspiration
    • forced expiration
  9. this type of respiration is when the diaphragm contracts, lowering itself. The external intercostal muscles then contracts so the rib cage lifts up
    Quiet inspiration
  10. This tye of breathing is a passive process. The muscles relaxes and the elastic lung tissue springs back
    quiet expiration
  11. Along with the diaphragm, which muscles contract during forced inspiration?
    external intercostals and sternocleidomastoid and scalenus
  12. Which muscles contract during forced expiration?
    internal intercostal muscles and abdominal muscles
  13. True or false: the upper airways are INFERIOR to the epiglottis
    false: superior
  14. Which parts of the respiratory tracts are in the "conducting zone" where no gas exchange occurs, also called "dead space"
    Nasal cavities, pharynx (throat), larynx (voice box), trachea, primary bronchi -> secondary/third bonchii
  15. Which parts of the respiratory tracts has gas exchange?
    the respiratory broncholes including: alveoli, alveolar ducts and sacs
  16. This part of the respiratory tracts contains C-shaped cartilage discs
    trachea
  17. This part of the respiratory tract contains "rings"
    primary bronchii
  18. This part of the resiratory tract contains "plates"
    secondary bronchi
  19. What is the type of tissue in the nasal cavities?
    pseudostratified ciliated columnar epith. (PCCE)
  20. This part of the respiratory tract contains stratified squamous
    pharynx
  21. Along with the nasal cavities, this part of the respiratory tract contains PCCE
    Larynx
  22. This part of the respiratory tract contains simple cuboidal epith.
    Bronchioles
  23. This part of the respiratory tracts are simple squamous
    alveolar sacs and alveoli
  24. T or F: the PCCE cilia in the lower respiratory tracts beats down
    F: beats up
  25. This is where mucus is transported to larynx where you either cough it up or swallow it
    Mucociliar escalator
