  1. What does the respitory system bring into the body?
    needed oxygen
  2. what does the respitory system eliminate from the body?
    C02
  3. what transports the gases
    blood
  4. what is oxygen transported to?
    the tissues
  5. where is carbon dioxide transported to?
    lungs
  6. the space within and postierior to external nose
    nasal cavity
  7. muscular tube extending from the nasal cavity to the esophagus
    pharynx
  8. external openings leading to nasal openings
    external nares
  9. the repitory tube that extends from the larynx to the main primary branch
    trachea
  10. part of the respitory passageway located between the trachea and the pharynx. It keeps airway open and prevents food from entering airway
    larynx
  11. one of two large respitory tubes that branches from the trachea and enters a lung 
    right primary bronchus
  12. one of two large respitory tubes that branches from the trachea and enters a lung (left)
    left primary bronchus
  13. one of the paired respitory system organs in which gas exchange occurs (right)
    right lung
  14. one of the paired respitory system organs in which gas exchange occurs (left)
    left lung
  15. the muscle that seperates the thoracic cavity from the abdominopelivic cavity. It contracts during respiration.
    Diaphragm
  16. the serous membrane which covers the external surface of each lung
    viseral pleura
  17. the serous membrane which liunes the thoracic wall and the mediastinum and covers the superior surface of the diapragm on each side of the thoracic cavity
    parietal pleura
  18. the region of the thoracic cavity between the lungs
    mediastinum
  19. the slit-like space between the viseral and parietal pluerae
    plueral cavity
  20. serous lubricating fluid within the plueral cavity. Secreted by the pluerae
    plueral fluid
  21. what are the branching airways of the lungs called?
    Bronchial Tree
  22. one of the two large respitory tubes tubes (right and left) that branches from the trachea and enters a lung
    primary bronchus
  23. a respitory tube that branches from a main bronchus and leads iunto one lung lobe
    secondary bronchus
  24. respitory tube that branches from a secondary bronchus and leads to one bronchopulminary segment of the lung 
    terchiary bronchus
  25. a very small air passage without supporting cartilage
    bronchiole
  26. the smallest, final type of bronchiole in the conducting zone
    terminal bronchiole
  27. the lung region containing avioli, where gas exchange takes place
    respitory zone
  28. thin walled air filled sacs in which gas exchange takes place
    alveoli
  29. clusters of alveoli that open into a common space
    alveolar sac
  30. what vessels carry blood that is low in oxygen from the heart to the lungs 
    pulmonary arteries
  31. what blood vessels completely surround each alveolus
    capillaries
  32. what gases are exchanged between the air in the alveoli and the blood in the pulmonary capillaries
    oygen and carbon dioxide
  33. what vessels carry oxigenated blood back to the heart?
    pulmonary veins
  34. what is the strong attraction between water molecules at the surface of aveolar fluid called 
    surface tension
  35. what does surfactant do to the surface tension of alveolar fluid 
    lowers it
  36. what would an alveolus do if it were lined with pure watrer
    alveoli would have to be completely reinflated with every breath 
  37. what makes up respiratory membrane 
    • simple squamous epithelium 
    • endothelium of pulmonary capillary walls and thier basement membranes
  38. what does oxygen and carbondioxide do accrossthe respitory membrane?
    diffuse
