define tidal volume
the volume of air breathed in/out during a normal breath at rest
define expitory reserve volume (ERV)
the additional air that can be forcibly exhaled after the exhalation of a normal tidal volume
define inspiratory reserve volume (IRV)
the additional air that can be forcibly inhaled after the inhalation of a normal tidal volume
define residual volume
the volume of air that remains in the lungs after a maximal exhalation
define anticipatory rise
when heart rate increases before exercising because of the expectation of exercise. this is caused by the hormone adrenaline
does residual volume increase, decrease or stay the same during exercise
remain the same throughout
what happens to the tidal volume during exercise
becomes more frequent and breaths will be deeper
