the volume of air breathed in per breath (size of breath)
measured in litres
max is determined by the size of lungs
4

ventilation
A
the volume of air breathed in and out per minute
ventilation=respiratory rate x tidal volume
5

A
allows more o2 to be taken in by the body which will support aerobic atp production
