Answers
Upper airway consists of: - ANS-nose, oral cavity, pharynx, and larynx
What are the primary functions of upper airway? - ANS-1. To act as a conductor of air
2. Humidify and warm or cool the inspired air
3. Prevent foreign materials from entering the tracheobronchial tree
4. Serves as an important area in involved speech and smell
What is the primary function of nose? - ANS-filter, humidify, and warm inspired air
What are the hair follicles in nose called? - ANS-Vibraissae
The 2 nasal passages between the nares and nasopharynx is? - ANS-choanae
The 3 bony protrusions on the lateral walls of the nasal cavity is - ANS-Conchae
(superior, middle, inferior turbinates)
An accessory respiratory passage? - ANS-Oral cavity
vestibule - ANS-small outer portion between teeth and lips that extends to the
oropharnyx
The pharynx includes? - ANS-nasopharynx, oropharynx, laryngopharynx
Larynx is also known as - ANS-voice box
major structures in laryngopharynx - ANS-epiglottis, vocal cords, and esophagus
the vestibule opening into the trachea from the pharyx - ANS-Larynx
3 functions of the larynx - ANS-passageway for air, prevents aspirations of solids and
liquids, generates sound
After air passes though larynx it enters where? - ANS-Tracheobranchial tree
epiglottis of larynx - ANS-prevents food and drink from entering airway when swallowing
, Cartilaginous airways - ANS-serve only to conduct air between the external environment
and the sites of gas exchange
Vallecula - ANS-space between tongue and epiglottis that is an important landmark for
intubation
noncartilaginous airways - ANS-serve both as conductors of air and as sites of gas
exchange.
epithelial lining of trachea is? - ANS-mucous blanket and pseudostratified ciliated
columnar epithelium
lamina propria - ANS-submucosal layer of trachea
conducting zone or cartilginous layer - ANS-outer most layer of tracheobronchial tree
At what point does trachea divide into left and right bronchi? - ANS-Carina
Right mainstem bronchus - ANS-wider and more vertical bronchi where aspirated items
are most frequently found
Patient can not be intubated in this mainstem bronchi - ANS-Right mainstem bronchus
right main bronchus divides into? - ANS-3 lobar bronchi- upper, middle, lower
what bronchi branches off the lobar bronchi? - ANS-Segmental bronchi
How many segmental bronchi are in the right lung? - ANS-10 segments
How manty segmental bronchi in the left lung? - ANS-8
continued branches from segmental bronchi are called? - ANS-subsegmental bronchi
3 single cartilages of larynx - ANS-thyroid, cricoid, epiglottis
paired cartilages of the larynx - ANS-arytenoid, corniculate, cuneiform
What lobe is the lingula a part of? - ANS-left upper lobe
How many lobar bronchi are divided off left mainstem bronchi? - ANS-2
Cilia does what? - ANS-moves mucous toward the glottis
What part of the pharynx is the pharyneal tonsil in? - ANS-Nasopharynx
