Flashcards in Respiratory Deck (74):
cessation of breathing
impaired o2/co2 exchange (suffocation)
acute respiratory disorder w/ unusually sensitive conducting airways
inflammation of bronchial lining
chronic obstructive pulmonary disease
temporary/permanent lung disease of bronchial tree; characterized by chronic bronchitis and chronic airway obstruction
high CO2 in blood
low co2 in blood
viral infection of lungs (flu)
inflammation of pleurae and secretion of excess amounts of pleural fluid
mix of saliva and mucus coughed up from respiratory tract, often as result of infection
smallest delicate bronchioles and alveoli in lung
structure opening to alveolar ducts
air that can be voluntarily expelled at the end of the normal quiet respiratory cycle is called
expiratory reserve volume (ERV)
which gas has highest partial pressure o2, co2, hydrogen, or nitrogen
active tissues get how many times more o2 than inactive
inflation and deflation reflexes
compliance increase with age because of...
deterioration of elastic tissue
break b/w left and right main/primary bronchus
thing that hangs in back of throat
what trap door thingy blocks trachea when eating
where does lower airway start?
muscle of breathing
which chris is the greatest
what is chest cavity called
when you inhale is diaphragm flexed or relaxed
change in pressure leads to flow of...
what makes air rush into lungs
the outside air pressure
do cilia produce mucos
no, lower respiratory tract
what cells make surfactant
type 2 epithelial cells
cough receptors are located in what 2 places
carina and epiglottis
expiration is passive process or active process
what does compliance mean in lung tissue?
ability to expand
what's smaller: alveoli or bronchioles?
what is turkish saddle?
is epiglottis part of larynx?
are vocal folds part of larynx?
where is cribriform plate of ethmoid bone?
b/w nose and cranial vault
where are olfactory bulbs?
plate separates left and right nostrils
2 pairs of hooks in nose to provide expansion
what tonsil in nasopharynx?
what tonsil in oropharynx?
what tonsil at base of tongue?
another name for adenoids tonsils

3 and 6
respiratory mucosa created by...
sutostratiftied ciliated columnar cells
slit b/t left and right vocal folds
another name for fibrous
levels of branching in lower respiratory tract
functions of surfactant (2)
1. reduce surface tension
2. prevents collapse
lines that separate lobes of lung
secondary also called
outer surface of organs...
5 causes of pnemonia
1. acute bacterial (streptococcus)
2. legionnaires legionella pneumophila
4. aspiration pneumonia
5. lobar/broncho pneumonia
severe acute respiratory syndrome
bacteria for TB
another name for legions
3 lower respiratory disorders
bronchitis, pneumonia, TB
process of air flowing into lungs during inspiration (inhalation) and out of lungs during expiration (exhalation)
lung volume representing normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied
additional amount of air that can be expired from lungs by determined effort after normal expiration
inspiratory reserve volume
maximal amount of additional air that can be drawn into lungs by determined effort after normal inspiration
volume of air still remaining in the lungs after most forcible expiration possible and amounting usually to 60-100 in.
volume where lungs will collapse
total amount of air that can be drawn into lungs after normal expiration
functional residual capacity (FRC)
volume of air present in lungs at end of passive expiration
total lung volume
mixture of non-reacting gases, total pressure exerted is equal to sum of partial pressures of individual gases
hypothetical gas whose molecules occupy negligible space and have no interactions, and that consequently obeys the gas laws exactly
pressure and volume of gas have an inverse relationship, when temperature is held constant
