This flashcard links increased oxygen demand to an increase in tidal volume (the amount of air inhaled or exhaled in a normal breath) which uses more of the vital capacity (the maximum amount of air a person can expel from the lungs), leading to an increased breathing rate to meet the higher oxygen requirements.

| Front | Link between O2 demands, tidal volume, vital capacity and breathing rate 3.1.1(e) |
|---|---|
| Back | As O2 demands inc, tidal vol inc (takes up more of vital capacity) so breathing rate inc to meet higher O2 demands |
