Biology · Secondary 3 · Easy · Oxygen debt
After a 400 m race, a runner is breathing rapidly and deeply for several minutes. This is mainly to

- repay the oxygen debt by oxidising lactic acid
- cool the body by removing excess carbon dioxide
- stop aerobic respiration and start anaerobic respiration
