lecture 12 Flashcards
3 phases of respiration
- pulmonary ventilation (inhale/exhale)
- external exchange of gas (alveoli & blood)
- internal exchange of gas ( blood to cell )
most important part of inhalation
diaphragm (inhalation active)
most important part of exhalation
intercostal ( exhalation passive )
upper respiratory tract
-nasal cavity
-pharynx
-larynx
lower respiratory tract
-trachea
-primary bronchi
-lungs
how many lobes in right lung
3 lobes
how many lobes in left lung
2 lobes
5 nasal cavities
- nostril
- nasal septum
- mucus membrane
- conchae or turbinate
- sinuses
sinuses
2 frontal
2 maxillaries
2 ethmoidal
2 sphenoidals
where is the epiglottis located
on top of the larynx
glottis
space when epiglottis is away from the larynx
carina
bifurcation of trachea
3 types of cells in alveolar wall
- type l (squamous alveolar) - form structure
- type ll (great alveolar) -secrete pulmonary surfactant
- macrophages - destroy bacteria
hypernea
increase depth & rate of breathing
hypopnea
decrease depth & rate of breathing
kyssmaul respiration
deep and labored breathing patterns
cheyne stroke respiration
deeper & sometimes faster breathing followed by a gradual decrease resulting in temporary apnea
