lab 3 - respiratory/urinary Flashcards
humidify, warm, filter, and act as a conduit for inspired air, as well as protect the respiratory tract through the use of the mucociliary system
nasal cavity
3 folds of tissue on lateral
walls of nasal cavity
conchae/turbinates
Superior portion of the
pharynx, Lined with Pseudostratified
epithelium, Contains pharyngeal
tonsils and auditory tubes
nasopharynx
Middle portion of the
pharynx, Contains palatine and
lingual tonsils
Oropharynx, Stratified
squamous epithelium
oropharynx
Inferior portion of the
pharynx, Stratified
squamous epithelium, Esophagus begins here
Laryngopharynx
voice box, Sound production
larynx
superior, Diverts food/water
away from airway,Composed of elastic cartilage
epiglottis
Opening within larynx, Formed by two sets of folds, Sound
Glottis
Inferior to Thyroid
cartilage, Connects larynx to
trachea, Form posterior portion
of larynx
cricoid
windpipe, Branches into right and left primary bronchi, ciliated
pseudostratified epithelium
trachea
3 lobes, Superior, middle, and
inferior, Separated by
horizontal and oblique
fissures
right lung
2 lobes, Superior and inferior, Separated by an oblique fissure
left lung
cavity on lungs
visceral
lines rib cage
parietal
Branch to form Secondary bronchi (lobar), 1 secondary bronchus goes to each lobe
primary bronchi
Branch to form Tertiary bronchi (segmental)
secondary bronchi
Eventually branch into Bronchioles, supplies air to a single bronchopulmonary segment
tertiary bronchi
Tubes that bring air into and out of lung
bronchial tree
Tiny air-filled
pockets within
the lungs where
all gas exchange
takes place
alveoli
Chambers connected to many
individual alveoli
alveolar sacs
Make up the walls of the
alveoli, Thin, delicate, 95% of alveolar surface area
type 1 alveolar cells
“Great Alveolar” cells, Secrete surfactant, Repair damaged epithelium
type 2 alveolar cells
dust cells, Monitor alveolar
environment, Engulf particles and
pathogens
macrophages
Thin membrane where gas
exchange takes place between
alveoli and pulmonary capillaries
respiratory membrane
