true
True or false
The lungs are elastic and thus have a
tendency to recoil inward.
True
true or false
Expansion of the chest cavity also causes
the lungs to expand.
true
True or false
When pressure inside the lungs is higher
than the atmospheric pressure, air will flow
out of the lungs.
During inspiration, air flows into the lungs the pressure inside the lungs is less than the atmospheric pressure.
because:
-a measure of the stretchability of the lungs.
-Patients with emphysema have increased compliance compared to normal
Which of the following statements is/are patients.
TRUE about compliance? -Restrictive lung disorders are characterized by decreased compliance.
tidal volume
The most efficient way to increase alveolar
ventilation is to increase:
false
True or false
Patients with restrictive respiratory
disorders have decreased vital capacity but
increased total lung capacity.
true
true or false
Pneumonia and pulmonary edema are
examples of restrictive respiratory
disorders.
40 mmHg; 40 mmHg
The partial pressure of carbon dioxide in
arterial blood is ________; whereas the
partial pressure of oxygen in venous blood
is ________.
increased partial pressure gradient
Which of the following would increase the
diffusion rate of gases between the alveoli increased ventilation-perfusion coupling
and the blood?
decreased O2 in the area causes vasoconstriction
When there is poor airflow to an alveolus,
which one of the following occurs to
maximize gas exchange in that area?
, bound to hemoglobin; bicarbonate
Most of the oxygen in the blood is
__________; and most carbon dioxide is
transported as _______.
left; loaded onto
Decreasing the temperature will cause the
oxygen-hemoglobin dissociation curve to
shift to the __________. This means that
oxygen is more easily
_______hemoglobin.
Carbon monoxide (CO) is so deadly prevents O2 from binding hemoglobin.
because it:
The fact that hemoglobin will unload more the bohr effect
O2 when acidity increases is called:
acidosis; hyperventilates
When carbon dioxide levels in the blood
decrease, this causes _________, so the
body __________ to correct the problem.
the body will try to compensate by breathing more slowly
When hyperventilating respiratory alkalosis will occur
false
true or false
In metabolic acidosis, central
chemoreceptor firing rate will increase to
cause the ventilation rate to increase.

Which one of the following is NOT a
function of the respiratory system?
assist in venous and lymph return
regulate blood Ca2+ levels
produce sound
regulate blood pH
nasal conchae
Which structure creates turbulent airflow in
the respiratory tract in order to warm,
cleanse, and humidify the air?
hyaline cartilage
The C-shaped rings of the trachea that
provide support so that it doesn't collapse
during inhalation are made of:
larynx

folds are all components of which structure
in the respiratory system?
