The flashcards below were created by user hughes7 on FreezingBlue Flashcards. What would you like to do?


  1. What are the Functions of the respiratory system?
    External and internal respiration and exchanging of the gases
  2. Name the organs in order that air flows thru on its way to the alveolar from the nostril
    Nostril-
  3. Name the parts of the conductive zone and the respiratory zone.
    nostrils to the terminal bronchiole- conducting zone

    respiratory bronchole to alveolar ducts, alveolar sacs & alveoli make up the respiratory zone.
  4. Name the parts of the pharynx
    Naso , oro  and laryngel
  5. name the cartilages of the larynx
    ayretenoid cartilage, thyroid, cricoid, corniculates made of hylaline cartilage.
  6. describe the anatomy of the trachea.
    Cartilage is C shaped and not completely closed. open posteriorly and are that way because of the esophagus .
  7. describe how the histology changes in the bronchi ole tree as the passages become smaller
    loose cartilage and gain smooth musucle

    and psudo stratifeded gets smaller
  8. what is the respiratory membrane composed of
    • capillary 
    • basement membrane
    • aveolar epitheium
  9. how does surfactant reduce water tension?
    made of lipids. layer in outside and slams wall on outside
  10. what are the functions of the pleaure
    reduce friction. and hold fluid
  11. What is the function of the lungs
    • -distribute air
    • -gas exchange
    • -and provides an air tight bag so the thorax can push and pull on.
  12. which muscles are used for inspiration
    Diaphram, scalenes,
  13. which muscles are used in expiratory respiration
    none, its a passive breath
  14. what msucles are used in forced exhalation
    • Internal intercostals
    • Diaphragm
    • rectus abdominus
  15. describe the function of the brainstem respiratory centers.
  16. what are the principles that allow air to flow in and out of the lungs?
  17. describe the anatomical changes that happens during inspiration
    Inspiration muscles contract,diaphragm lowers, and ribs elevate. the lungs are stretched and the intrapulmonary and thoracic cavity volumes increase. intrapulmonary pressure drops to -1 mmHg. the air is then sent into the lungs until intrapulmonary pressure is 0 and equal to atmospheric pressure.
  18. what factors cause a resistance to airflow?
    • Size of bronchi-oles 
    • pulmoanry compliance
    • surface tention
  19. what does a spirometer measure?
    the amount and speed of air that can be inhaled and expirated
  20. what are respiratory volumes and capacities
    Tire and vift
  21. Which of the 3 divisions of the pharynx is used only for respiratory functions?
  22. the structure that prevents the entry of liquids or solid food into the air passageway during swallowing?
  23. The amout of air moved into or out of the lungs during one breath is called
    Tidal Volume
  24. what causes cystic fibrosis?
    Genetics
  25. During exhalation, the diaphragm moves
  26. the narrow opening through which inhaled air leaves the pharynx and enters the larynx is the.
  27. The hard palate separates
    palatine and maxilla bone
  28. Functions of the respiratory system include.
  29. Air entering the body is filtered, warmed and humidified by:
  30. inflammation of mucus membranes in bronchial tubes and produce excess mucus
  31. diffusion of gases between blood and interstitial fluid across the respiratory membrane
  32. Mucosa-covered projections of nasal cavity
    nasal conchae
  33. lines thoracic cavity
  34. left lungs
    have 2 lobes
  35. inflammation of pleural membranes
    plerisy
  36. chronic inflammatory disorder caused by the airway sensitivity that led the airway obstructions.
  37. describe the anatomical changes that happens during expiration
    inspiratory muscles relax diaphram rises and ribs desend.elastic lungs recoil passively and the thoracic and intrapulmonary volumes decrease and intrapul pressure is +1. air is then leaves the lungs until the intrapulmonary pressure is is zero.
