Answer 3

D

Question 4

Which of the following respiratory volumes or capacities has the highest volume?

A) Inspiratory reserve volume
B) Vital capacity
C) Functional residual capacity
D) Inspiratory capacity
E) Expiratory reserve volume

Question 5

Boyle's law states that

A) the thinner the respiratory membrane, the faster diffusion will occur.
B) the pressure of a gas is proportional to its volume.
C) the higher the temperature of a gas, the greater its volume will be.
D) the higher the temperature of a gas, the higher its pressure will be.
E) the pressure of a gas is inversely proportional to its volume.

Question 6

Which of the following is not true of inspiration?

A) Inspiratory reserve volume is much lower than expiratory reserve volume.
B) Inspiration results from contraction of the diaphragm and the external intercostal muscles.
C) Enlargement of the thoracic cavity reduces the pressure in the lungs, leading to air entering the thoracic cavity.
D) The anatomic dead space is about 30% of the inhaled tidal volume.
E) All of these are true of inspiration.

Question 7

Respiratory capacities are the sums or two or more volumes.

Question 8

The ________ can be calculated by multiplying breathing rate by tidal volume.

A) alveolar ventilation rate
B) anatomic dead space
C) inspiratory reserve volume
D) minute respiratory volume
E) inspiratory capacity

Question 9

Inspiratory reserve volume (IRV) can be calculated by subtracting the tidal volume (TV) from the vital capacity (VC).

Question 10

Which of the following respiratory volumes or capacities is equal to the sum of the expiratory reserve volume (ERV) and the residual volume (RV)?

A) Total lung capacity (TLC)
B) Vital capacity (VC)
C) Inspiratory capacity (IC)
D) Expiratory capacity (EC)
E) Functional residual capacity (FRC)

Question 11

Which of the following is not a muscle of forced expiration?

A) Interosseous portion of the internal intercostals
B) Rectus abdominis
C) Pectoralis minor
D) External oblique
E) All of these are muscles of forced expiration.

Question 12

The respiratory division is the portion of the respiratory passageway that

A) performs gas exchange.
B) is located superior to the trachea.
C) is located within the thorax.
D) provides for airflow, but not gas exchange.
E) is located inferior to the trachea.

Question 13

Which of the following respiratory volumes and capacities can not be measured with a spirometer?

A) Vital capacity
B) Expiratory reserve volume
C) Residual volume
D) Tidal volume
E) All of these can be measured with a spirometer.

Question 14

The volume of inhaled air that never reaches the alveoli is called the

A) functional residual capacity.
B) tidal volume.
C) anatomic dead space.
D) inspiratory reserve volume.
E) alveolar dead space.

Question 15

Which of the following muscles is mainly responsible for elevating the sternum during forced inspiration?

A) Sternocleidomastoid
B) Pectoralis minor
C) External oblique
D) Diaphragm
E) External intercostal

Question 16

Normal, quiet expiration does not require any muscle contraction; it is entirely a result of muscle relaxation and elastic recoil.

Question 17

All of the following factors would be expected to increase a person's vital capacity except

A) being male instead of female.
B) getting older.
C) being taller.
D) getting regular exercise.
E) being in good general health.
