volume of air inspired or expired per breath
changes during exercise: tidal volume
increases
inspiratory reserve volume
volume of air forcibly inspired after a normal breath
changes during exercise: inspiratory reserve volume
decreases
expiratory reserve volume
volume of air forcible expired after a normal breath
changes during exercise: expiratory reserve volume
decreases
residual volume
volume of air remaining in the lungs after max expiration
changes during exercise: residual volume
stays the same
spirometer
device that is used to measure the volume of air inspired and expired by the lungs
on a spirometer what happens to the peaks during exercise
peaks get closer
minute ventilation
volume of air inspired or expired in a minute
TVxf
changes during exercise: minute ventilation
increases
