MULTIPLE CHOICE

1. The body’s mechanism for conducting air in and out of the lungs is known as which of the

following?

a. External respiration

b. Internal respiration

c. Spontaneous ventilation

d. Mechanical ventilation

ANS: C

The conduction of air in and out of the body is known as ventilation. Since the question asks

for the body’s mechanism, this would be spontaneous ventilation. External respiration

involves the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the

pulmonary capillaries. Internal respiration occurs at the cellular level and involves movement

of oxygen from the systemic blood into the cells.

REF: pg. 2

2. Which of the following are involved in external respiration?

a. Red blood cells and body cells

b. Scalenes and trapezius muscles

c. Alveoli and pulmonary capillaries

d. External oblique and transverse abdominal muscles

ANS: C

External respiration involves the exchange of oxygen and carbon dioxide (CO2) between the

alveoli and the pulmonary capillaries. Internal respiration occurs at the cellular level and

involves movement of oxygen from the systemic blood into the cells. Scalene and trapezius

muscles are accessory muscles of inspiration. External oblique and transverse abdominal

muscles are accessory muscles of expiration.

REF: pg. 2

3. The graph that shows intrapleural pressure changes during normal spontaneous breathing is

depicted by which of the following?

 2 / 3

a.

b.

c.

d.

ANS: B

During spontaneous breathing, the intrapleural pressure drops from about 5 cm H2O at endexpiration to about 10 cm H2O at end-inspiration. The graph depicted for answer B

shows that change from 5 cm H2O to 10 cm H2O.

REF: pg. 3

4. During spontaneous inspiration alveolar pressure (PA) is about: ________________. a. 1 cm

H2O

b. +1 cm H2O

c. 0 cm H2O

d. 5 cm H2O

ANS: A
