airway Flashcards
respiration
providing oxygen to the body and removing carbon dioxide through nhalation and exhalation
respiratory epithelium?
pseudostratified, ciliated, columnar
with goblet cells that secrete mucos
deviated septum
sinus drainage may be comprimsed
olfactory epithelium?
these are restricted to the roof and adjacent lateral wall of of the nasal vavity
they are for smell
superior, middle, inferior conchae function?
- provide turbulance
- increase the surface area for air flow
- heat exchange
nasolacrimal duct
enters the nasal cavity to drain tears from the conjunctiva of the eye.
THIS IS WHY YOU BLOW YOUR NOSE WHEN YOU CRY!
the anastamoses within the nose is branches of what arteries?
external carotids and internal carotids.
nasopharynx
transports air
oropharynx
transports air, food and fluid
(they must be seperated)
what direction does air, fluid and water go after the oropharynx?
- food and fluid = laryngopharynx
- air = larynx
why would the laryngeal diameter be altered?
larynx
- to allow the passage of air
- control air flow for speech and raising intra-abdominal pressure.
where is the site of emergency access to the airway?
cricothyroid membrane
aryepiglottic fold
epiglotic fold
upper edge of the quadrangular membrane
vestibular fold
lower edge of the quadragular membrane
vocal fold
upper edge of the cricothyroid membrane.
epiglotic fold?
- this will open to breathe
- when we swallow it is closed preventing food and fluid moving into the larynx into the lungs
PROTECTIVE SPHINCTER
saccule
these are mucosal glands which help to lubricate the vocal folds
within the larynx
