respiratory system Flashcards
functions of the respiratory system
regulate blood ph
receptors for sense of smell
filters, warms and moistens inspired air
produces sounds
rids the body of some water and heat in exhaled air

upper respiratory tract/conductive portion
nose
nasal cavity
pharynx
larynx
lower respiratory tract
larynx
trachea
bronchi
lungs
conductive portion of the respiratory system
system of tubes which carry air to and from the lungs
respiratory portion
gas exchange area
what epithelium is the conductive portion of the respiratory tract
pseudostratified ciliated columnar epithelium
what is the nasal bone
cartilage
what is the openings of nose
external nares
what is the nasal vestibule
divided by the septum and contains nose hairs
where you pick buggas
different nasal conchae
superior
middle
inferior
three types of cells in olfactory epithelium
sustentacular cells
basal cells
olfactory cells
what type of cells are olfactory cells
bipolar neuron=one dendrite, one axon
what is the pharynx
tube connecting nasal and oral cavities and the larynx
what is the upper part of the pharynx called
nasopharynx
what is the middle part of the pharynx called
oropharynx
what is the bottom of the pharynx called
laryngopharynx
what is the epiglottis and what does it do
small piece of cartilage which opens and closed to ensure nothing but air gets into the lungs
what are the cartilage in the larynx called
thyroid
epiglottis
cricoid
arytenoid
corniculate
cuneiform
what are the two pairs of folds in the vocal cords
vestibular/ventricular folds
vocal folds
what are the false vocal cords
vestibular/ventricular folds
where does the trachea run
from the larynx to the superior border of T5
what are the three layers of the bronchi called and what do they split into
primary bronchi split into left and right bronchus
the secondary bronchi split into 3 right and 2 left bronchus
the tertiary bronchi split into 10 in each lung
what epithelium is in the bronchial tree
simple non-ciliated cuboidal epithelium
in the right lung what are the lobes called and what bronchus do they receive from
superior lobe- recieves from the superior lobar bronchus
middle lobe-receives middle lobar bronchus
inferior lobe receives blood from the inferior bronchus
lobes of the left lung
superior and inferior lobes
what do the respiratory bronchioles form
respiratory bronchioles->alveoli ducts->alveolar sacs->alveoli
what epithelium is type 1 alveoli
simple squamous epithelium
what epithelium is type 2 alveoli
simple cuboidal non-ciliated epithelium
