Pulmonary Physiology

Question 1

Tidal volume

Answer 1

is the volume of air that moves
through the lungs between a normal inhalation
and exhalation

Question 2

Inspiratory reserve volume

Answer 2

is the maximum
volume of air that can be inhaled further after a
normal inhalation is already taken in.

Question 3

Expiratory reserve volume

Answer 3

is the maximum
volume of air that can be exhaled further after a
normal exhalation is already released.

Question 4

Expiratory reserve volume

Answer 4

is the maximum
volume of air that can be exhaled further after a
normal exhalation is already released.

Question 5

Residual volume

Answer 5

is the minimum amount of air
that needs to be present in the lungs to prevent
collapse.

Question 6

Functional residual capacity

Answer 6

is the entire volume
of air still present in the lungs after a normal
exhalation. It is also the sum of the expiratory
reserve volume and the residual volume.

Question 7

Vital capacity

Answer 7

is the maximum amount of air that
can be exhaled after a maximum inhalation. It is
the sum of the inspiratory reserve volume, tidal
volume, and expiratory reserve volume.

Question 8

Total lung capacity

Answer 8

is the sum of the vital
capacity and the residual volume: it is the
maximum volume the lungs could possibly hold at
any given time.
