Lung Capacity

Was there a difference between lung volumes for male and female?

The male average had a higher lung volume than the average female; this is because males have more capacity in their chest cavity and also depends on height

Total Lung Capacity (TLC)

maximum amount of air contained in lungs after a maximum inspiratory effort A) VC (Vital Capacity) + RV (Residual Volume) = TLC (Total Lung Capacity)

What does a spirometer do?

measures volume of air inspired and expired by the respiratory system

Vital Capacity (VC)

the greatest volume of air that can be expelled from the lungs after taking the deepest possible breath. F) TV (Tidal Volume) + IRV (Inspiratory Reserve Volume) + ERV (Expiratory Reserve Volume

Functional Residual Capacity (FRC)

the volume of air remaining in the lungs after a normal tidal volume expiration ERV (Expiratory Reserve Volume) + RV (Residual Volume)

expected male vital capacity

4800

expected female vital capacity

3100

Residual Volume (RV)

E) Amount of air remaining in the lungs after a forced exhalation

Minute Volume (MV)

Amount of air moving in and out of lungs each minute (~8,000 mL); TV x RR = MV

Tidal Volume (TV)

B) amount of air inhaled or exhaled with each breath under resting conditions

Inspiratory Reserve Volume (IRV)

C) Amount of air that can be forcefully *inhaled* after a normal tidal volume inhalation

Expiratory Reserve Volume (ERV)

D) Amount of air that can be forcefully *exhaled* after a normal tidal volume exhalation
