  1. What are the 2 major respiratory division
    • upper respiratory tract (head & neck)
    • Lower respiratory tract (thoracic cavity)
  2. What are the componentes of the upper respiratory tract?
    • head & neck
    • nasal cavity
  3. where does the upper respiratory tract starts
    nostrils aka nares (naris)
  4. the nasal is separated by
    nasal septum
  5. Why do we breathe through the nose?
    • filters, warms and moisturizes the air
    • keeps the sinus clear
  6. nasal conchae (turbinate bone) is part of what bone and name the 3 parts of the bone
    • nasal conchae is part of the ethmoid¬† bone
    • superior
    • middle
    • inferior
  7. what does the air passage way of the nasal forms
    forms the 3 nasal meatuses (tube)
  8. What is the paranasal sinuses
    • it is the spaces inside the bones
    • sinuses are connected by tubes to the nasal cavity
    • the spaces also help cools the brain
  9. What are the 4 main bones that have sinuses?
    • frontal
    • sphenoid
    • maxillary
    • ethmoid
  10. This bone is one of the 4 main bone that have sinuses and is where you find the pituatary gland. The pituatory sits behind this bone.
  11. This is the largest sinues of the 4 main bones that have sinuses
  12. the maxillary bone is also known as the
    maxillary antrum
  13. This helps block the nasal cavity
  14. what are the 3 sections of the Pharynx
    • nasopharynx
    • oropharynx
    • larynogopharynx
  15. this section has the eustachian tube aka auditory tube also includes the pharyngeal tonsil (adenoid tonsils)
  16. this section contains 2 palatine tonsils and 2 lingual tonsils
  17. this section includes the epiglottis
  18. what type of tissue is the epiglottis made of
    connective tissue made of cartliage
  19. what does the epiglottis flap covers?
    the glottis
  20. what is the opening to the larynx
  21. what closes the glottis when swallowing and involved in choking?
    the epiglottis
  22. This is known as the voice box
  23. The thyroid cartilage is known as the
    Adam's Apple
  24. What is the cartilage under the thyroid cartilage
    cricoid cartliage
  25. What type of cartilage is in the larynx
    arytenoid cartilage in the larynx
  26. what structure is after the cricoid cartilage?
    vocal cords
  27. This is the inner vocal cord and is made of cartilage. This is known as the
    true vocal cord
  28. this is the outer vocal cord and is made of vocal folds. This is known as the
    false vocal cord
  29. This separates the upper and lower respiratory tract and has rings of cartilage that are c shaped?
  30. y shaped cartilage at the bottom of the trachea
  31. the 3 branches of the bronchi is called the
    bronchial tree
  32. what are the 3 branches of bronchi or known as the bronchial tree
    • primary bronchi (2)
    • secondary bronchi (5) 3 on right/ 2 on left
    • tertiary bronchi (10)
  33. The tertiary bronchi is connected to these smaller tubes cartilage that gets smaller
  34. the terminal bronchials leads to
    air sacs
  35. are there any gas exchange in the terminal bronchioles?
  36. where does the gas exchange begin?
    in the respiratory bronchioles which have alveoli on the surfaces. Its in the alveoli is where the gas exchange occurs
  37. what are cluster of alveoli
    air sacs
  38. where does the gas enters from
    Oxygen enters the blood from air in the aveolus
  39. O2 enter blood from air in the the aveolus then what gas leaves the blood stream and enters air
  40. what type of tissue is the aveoli
    simple squamos epithelium. it is one cell thick. very thin
  41. this is the wall of the aveolus and walls of the capillary
    respiratory membrane
