this is due to a process called respiration.when the organism respires, it uses O2 from the air to burn glucose in your body to produce energy.in the process CO2 is produced.this is why that when you expire there is more CO2 than O2

Probably there is mixing with incoming air.
Air is about 78 per-cent N2, 20 per-cent O2 and 1 per-cent argon. The rest, more or less is reserved for water vapor, CO2, which at 350 ppm is about 0.003 per-cent in air, and other gases.
