BIO 669 Quiz 5 Questions With Complete
Solutions
A patient has a history of emphysema and has
hyperinflated lungs. Which of the following would
be true regarding this patient?

The compliance within the apex of the lung of a
standing person would be ___ than the base of the
lung
Less than
The space between the lungs that include the
heart, esophagus, and the great vessels is termed
Mediastinum
Which of the following is true regarding acute
respiratory syndrome (ARDS)
It can cause severe pulmonary edema
Pulmonary fibrosis is most likely to result in all of
the following except
Oxygen toxicity
Emphysema results from
An infected pleural effusion
A reduced oxygenation of the blood is termed
, Hypoxemia
Along with respiratory bronchioles, the ___ is a thin
walled balloon-liked structure that acts as the
primary unit of gas exchange
Alveolus
The most common feature as a result of
hyperventilation is
Hypocapnia
The pores of Kohn play a role in
Allowing air to pass from one alveoli to another,
allowing equal distribution of air
What effect would acidemia at the alveolar level
have on the pulmonary artery
Decreased blood flow (vasoconstriction) to the area
While most alveolar perfusion is under control of
local humoral conditions, widespread decrease in
PaO2 (alveolar O2) is likely to result in
Pulmonary artery contriction (pulmonary
hypertension)
A pulmonary embolus creating alveolar dead space
will likely have which of the following effects
High V/Q ratio
