CHPT 23: respiration Flashcards
functions of the resp sys
- gas transport and exchange
- regulate blood PH
- has receptors for sense of smell
- filters inhaled air
- produces sound
- elimantes small amount of water and heat in exhaled air
- nasal cavity
- pharynx
- tonsils
belong to which resp tract
- upper resp tract
organs in the lower resp tract are
- larynx
- trachea
- bronchi
- lungs
function of conduction zone
- filter, warm, moisten and conduct air into lungs
organs in the conduction zone
- nose / + nasal cavity
- pharynx
- larynx
- bronchi
- bronchioles
- terminal bronchioles
gas exchange is the function of which zone
resp zone
organs in the resp zone
- resp bronchioles
- alveolar ducts
- alveolar sacs
- alveoli
overall function of nose / + nasal cavity
- filter, humidify air
- olfactory sense
- allow air in to the body
structures of the nasal cavity
- internal naris
- external naris
- nasal meatuses
- olfactory epithelium
- nasal concha
- nasal vestibule
which nasal cavity structure contains nose hair
nasal vestibule
function of olfactory epithelium
detect smell
what structure does air enter through
external naris
nasal concha function
- covered by nasal mucous membrane + bv
- filters air
nasal meatuses are
- air passage
- contain mucous mem + bv
internal naris function
- separates nasal cavity from pharynx
which structure houses tonsils
pharynx
nasopharynx function
- direct air OR
- prevent air from getting in while eating (uvula)
what ear structure is located in the nasopharynx
-Eustachian tube
function of Eustachian tube in nasopharynx
- connects nasopharynx to tympanic cavity
structures in the nasopharynx
- uvula
- pharyngeal or adenoid tonsils
- eustachian tube
pharyngeal or adenoid tonsils location
nasopharynx
which pharynx cavity allows passage of food and air and fluid + is digestive and respiratory
oropharynx
what tonsil are found in the oropharynx
- palatine
- lingual tonsils
which pharynx cavity has no tonsils
larynopharynx
what nerves are found in larynopharynx
glassopharyngeal (CN9) and vagus nerve (10)
location of epiglottis
larynopharynx
functions of larynopharynx
- digestive and resp
- allow things to pass to esophagus
which structure depresses against nasal cavity and blocks air from getting in and secretes saliva
uvula
function of epiglottis
block entry of food or air from getting in to the wrong structure
which cartilages of the larynx are unpaired
- thyroid
- epiglottis
- cricoid
which cartilages protect and support the larynx
unpaired cartilages
- thyroid
- epiglottis
- cricoid
which unpaired cartilages make up the Adams apples ( laryngeal prominere) and prevents choking and provides protection
thyroid
- aryteniod
- cuneiform
- corniculate
are ___ cartilages of the larynx
paired
function of paired cartilages of larynx
position larynx for sound production
overall function of the larynx
- produce sound
- connect larynogophyarynx with trachea
which lobe has no middle lobe
L Lung
what forms the apex in lungs
superior part
base forms the __ in lungs
base
function of oblique fissure in L Lung
divde superior and inferior lung
which fissure separates the superior, middle and inferior lobe in R Lung
oblique fissure
which lung has the cardiac notch
L Lung
function and location of horizontal fissure
- divides superior lobe from the middle
R Lung
types of epithelial cells in the lungs
- type 1 and 2 alveolar cells
which epithelial cell in the lungs is responsible for gas exchange
type 1 alveolar cells
function of type 2 alveolar cells
- secret surfactant that reduces surface tension and prevents lungs from collapsing / sticking
which cell is responsible for for engulfing bacteria in lungs
alveolar macrophage
