Which of the following pairs are mismatched?
|
|
tidal volume-the amount of air exchanged by lungs at rest
|
|
|
residual volume-the amount of air someone can consciously exchange with the environment
|
|
|
inspiratory reserve volume-additional amount of air that can be consciously inhaled
|
|
|
expiratory reserve volume-additional amount of air that can be consciously exhaled
|
Explanation:
Detailed explanation-1: -Functional residual capacity (FRC), is the volume remaining in the lungs after a normal, passive exhalation. In a normal individual, this is about 3L.
Detailed explanation-2: -Vital Capacity(VC) It is the total amount of air exhaled after maximal inhalation. The value is about 4800mL and it varies according to age and body size. It is calculated by summing tidal volume, inspiratory reserve volume, and expiratory reserve volume. VC = TV+IRV+ERV.
