1. Upper tract
    • noise,
    • nostrils,
    • mouth,
    • pharynx,
    • epiglottis (respiratory safeguard)
    • larynx (voice box),
    • trachea( windpipe).
  2. fine particlates
    such found in smoke and haze are 2.5 micometers in diameter and smaller.
  3. trachea length
    • 11cm long,( 4in) 2-2.5cm (in) diamiter.
    • diameter is greater in men then women and adults then children.
    • air-noise/mouth-thru larynx, down trachea-our lungs.
  4. approximate adult respiratory rate
    12-20 times per minute.
  5. approximate number of alveoli in lungs?
    • 350 million right aveoli.
    • 300 million left aveoli because of large size of heart.
    • total 600 million.
  6. phrenic nerve
    the diaphragm is the major muscle of resperation is stimulated by the phrenic nerve.
  7. lungs primarly exchange o+co2
    lungs are complex organs they take gas that ur body needs to get rid of (CO2carbon dioxide) & exchange it for gas that ur body can use (O2 oxygen)
  8. Epiglottis
    • flab of cartlidge lying behind the tongue & in front of the entrance larynx (voice box)
    • at rest, upright and air passes thru larynx and into respiratory system.
    • swallowing, it folds back to cover the entrance to larynx, preventing food and drink from entering the trachea.
  9. nasopharnxy
    • above the mouth
    • only passage way for air alone
  10. oropharynx
    • middle region
    • air inhaled, food & liquid pass thru this region.
  11. laryngopharynx
    lowest region of pharynx
  12. list 3 ways that sinunes help us
    • -reasonance for the voice ( A,E,I,O,U)
    • -hollow areas or cavity in the bones of the skull that lined with mucus membranes for protection.
    • -sinuses are inflammed & filled with the mucus the voice has a different quality
  13. 5 risk factors of asthma

    • wheezing
    • chest tightness
    • reduce physical activity
    • chronic coughing
    • loss of appetitie and weight
    • fatigue
    • smoking (most common)
    • protein deficiency AAT
  15. 5 triggers of asthma
    • exercise - induced asthma
    • heart burn
    • smoking
    • infections
    • poor air - particles
  16. inhalable coarse particles
    such as found near roadways and dusty industries, as larger then 2.5micrometers and smaller than 10micrometers in diameter.
  17. pharynx (throat)
    • *responsable for adjoining the nasal cavity and oral cavity to the larynx and the esophagus.
    • *approximately 13cm(5in) long and is a shape of a funnel.
    • *it shares both respiratory and digestive functions.
  18. larynx(voice box)
    • product of voice can be thought of in term of three things:
    • production of air flow(respiration)
    • generation and resonance of sound(fine tunning)
    • articulation of voice.
  19. note
    • L 2 heart on this side because heart is large.
    • R 3
  20. sinuses location
    • frontal
    • ethmoid
    • sphenoid
    • maxillary
  21. alveoli (air sac)
    gas exchange of oxygen andcarbon dioxide takes place in the alveoli.
  22. risk factors of emphysema
    • smoking
    • age between 40-60
    • second hand smoke(passive)
    • occupational exposure to fumes or dust
    • indoor/outdoor pollution
  23. symptoms of asthma
    • shortness of breath
    • chest tightness
    • trouble sleeping(wheezing, coughing)
