The nose, pharynx, Conducting airways
larynx, trachea, bronchi,
and bronchioles all
comprise what?
The terminal bronchi, Respiratory Zone
alveoli, and alveolar
capillaries all comprise
what?
Transpulmonary pressures represent the difference
What is Transpulmonary
between the intrapleural pressure and the alveolar
pressure and how does it
pressure. They help maintain the patency (openness)
affect the muscles in the
of the smooth muscles area. Prevents the the
bronchi and bronchioles?
collapse of the airway
Sympathetic stimulation Beta-2 adrenergic receptors
mediated by what
receptors, leads to the
relaxation of bronchi
smooth muscle
promoting
bronchidialation?
During sympathetic Epinephrine
stimulation and
bronchodilation what
hormone is release?
,Parasympathetic Acetylcholine
stimulation via the vagus
nerve results in the
release of what
Neurotransmitter?
Parasympathetic bronchoconstriction
stimulation via the vagus
nerve results in
bronchodilation or
bronchoconstriction?
When lung cells in the bronchoconstriction
endothelium produce
inflammatory mediators
such as Leukotrienes,
does this promote
bronchoconstriction or
bronchodilation?
What do mast cells Histamines
release during
anaphylaxis?
What effect does the Constriction
histamine release during
anaphylaxis have on the
bronchi and bronchioles?
The pressure between Pleural pressure
the two linings if the
pleura (visceral and
parietal) is called the ____?
During inspiration -7.5 cm H2O
(expansion of the chest
cavity), pleural pressure
becomes more negative
reaching ____ cm H2O.
When is alveolar pressure When the glottis is open and the airway is
equal to atmospheric unobstructed (0 mm H2O)
pressure?
, What happens to alveolar Alveolar pressure decreases to about -1 cm H2O
pressure when during
inspiration when the
chest cavity expands and
the diaphragm contracts?
What happens to alveolar Alveolar pressure increases slightly to +1 cm H2O
pressure when during causing air to move out of the lungs
expiration when the chest
cavity recoils and the
diaphragm relaxes?
Breach of pleural space Pneumothorax
when atmospheric air
enters and equalizes
pressure to atmospheric
at 0 (-4 mm of Hg is lost)
- lung is unable to
expand, what is this?
What is the volume of Tidal volume (TV)
inspired and expired air
with each "normal"
breath?
What is the max effort of Inspiratory Reserve Volume (IRV)
air inspired after "normal"
inspiration?
What is the max effort of Expiratory Reserve Volume (ERV)
air expired after "normal"
expiration?
What is air left in the lung Residual volume
at the end of ERV
(Expiratory Reserve
Volume)?
What is forced vital The total amount of air which one can forcibly
capacity (FVC)? exhale
The amount of air Forced Expiratory Volume (FEV)
exhaled in the first
second of exhalation?
