Question

During exercise, your body consumes more oxygen. How does your body compensate for this?

Answer 1

Answer : During exercise muscles work harder, the body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, breathing has to increase from about 15 times a minute (12 litres of air) when resting, up to about 40–60 times a minute (100 litres of air) while exercising. The oxygen during exercise enters the bloodstream and is carried to muscles, where some of it is used immediately, and the rest is stored by a compound called myoglobin. Whether exercising or not, the oxygen in body is used to break down glucose and create the fuel for muscles called ATP.
