Tidal volume the volume of air that enters and
leaves the lungs at each natural resting breath.
Inspiratory reserve volume (IRV) - the volume of
air that can be taken in over and above the
normal inspired tidal volume.
Expiratory reserve volume (ERV) - the volume of
air that can be expelled over and above the
normal inspired tidal volume.…read more
Vital capacity (VC) - tidal volume + IRV + ERV
Residual volume (RV) - the volume of air left in the
lungs after the strongest possible expiration.
Total lung capacity (TLC) - the sum of the vital
capacity and the residual volume.
Inspiratory capacity (IC) - the volume that can be
inspired from the end of a normal expiration.…read more
= tidal volume x frequency of inspiration
The ventilation of the
lungs needs to supply all
the oxygen needed by the
tissues of the body and
remove the waste CO2.…read more
Control and regulation
The basic stimulus to inhale and exhale is
given by an area of the medulla known as the
respiratory centre. It involves a feedback
system based on the stretching of the bronchi
during breathing.…read more
