MULTIPLE CHOICE y
1. The body’s mechanism for conducting air in and out of the lungsis
y y y y y y y y y y y y
known as which of the following?
y y y y y y
a. External respiration y
b. Internal respiration y
c. Spontaneous ventilation y
d. Mechanical ventilation y
ANS: C y
The conduction of air in and out of the body is known as ventilation.
y y y y y y y y y y y y y
Since the question asks for the body’s mechanism, this would be
y y y y y y y y y y y
spontaneous ventilation. External respiration involves the exchange
y y y y y y y
of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the
y y y y y y y y y y y y
pulmonary capillaries. Internal respiration occurs at the cellular
y y y y y y y y
level and involves movement ofoxygen from the systemic blood into
y y y y y y y y y y y
the cells.

2. Which of the following are involved in external respiration?
y y y y y y y y
a. Red blood cells and body cells y y y y y
b. Scalenes and trapezius y y
muscles
c. Alveoli and pulmonary y y
capillaries
d. External oblique and y y
transverse abdominal muscles y y

External respiration involves the exchange of oxygen and carbon
y y y y y y y y

y y y y y y y y y
Internal respiration occurs at the cellular level and involves
y y y y y y y y y
movement of oxygen from the systemic blood into the cells.
y y y y y y y y y y
Scalene and trapezius muscles are accessory muscles of inspiration.

External oblique and transverse abdominal musclesare accessory
y y y y y y y y
muscles of expiration.

3. The graph that shows intrapleural pressure changes during
y y y y y y y
normal spontaneous breathing is depicted by which of the
y y y y y y y y y
following?
y
a. 5cm to 10cm yy y y y
b. -5cm to -10cm y y y
c. -5cm to 10cm yy yy y y
d. 5cm to -10cm yyy y y y
ANS: B y
During spontaneous breathing the intrapleural pressure drops
y y y y y y
from about -5 cm H2O at end-expiration to about -10 cm H2O at
y y y y y y y y y y y y y
end-inspiration. The graph depicted for answer B shows that
y y y y y y y y y
change from -5 cm H2O to -10 cm H2O.

4. During spontaneous inspiration alveolar pressure (PA) is about:
y y y y y y y
y .
a. - 1 cm H2O y y y
b. + 1 cm H2O y y y
c. 0 cm H2O y y
d. 5 cm H2O y y
ANS: A y
-1 cm H2O is the lowest alveolar pressure will become during
y y y y y y y y y y
normal spontaneous ventilation. During the exhalation of a normal
y y y y y y y y y
spontaneous breath the alveolar pressure will become +1cm H2O.

5. The pressure required to maintain alveolar inflation is known as
y y y y y y y y y
which of the following?
y y y y
a. Transairway pressure (PTA ) y y y
b. Transthoracic pressure (PTT) y y
c. Transrespiratory pressure (PTR) y y
