Accepted Answer

A)   hypoventilation
B)   hyperventilation
C)   apnea
D)   dyspneaE) A) and B)
F) None of the above

Question 3

Describe the changes in pressure and volume that lead to inspiration.

Accepted Answer

The diaphragm and external intercostal muscles contract upon stimulation by the phrenic and intercostal nerves. In doing so, the intrapulmonary volume (volume inside the lungs) increases. Gases within the lungs spread out to fill the larger space, decreasing the intrapulmonary pressure. Air follows the pressure gradient into the body until intrapulmonary pressure equals atmospheric pressure, and inspiration (inhalation) occurs. Air rushes into the lungs.

Question 4

Exchange of both oxygen and carbon dioxide through the respiratory membrane occurs by ________.

Accepted Answer

A)   osmosis
B)   simple diffusion
C)   facilitated diffusion
D)   active transport
E)   endocytosisF) B) and C)
G) A) and E) B

A)   inflammation and swelling of the tonsils
B)   air is not moistened, warmed, or filtered before reaching the lungs
C)   inability to propel mucus from the lungs to the throat
D)   nasal congestion and postnasal drip
E)   inability to produce mucusF) C) and D)
G) B) and C)

Question 6

Match the following definitions with their associated respiratory volume or capacity:
-Sum total of tidal volume, inspiratory reserve volume, and expiratory reserve volume

Accepted Answer

A)  vital capacity
