anything and everything that is in the air, your body just expelles everything that isn't O2
We breathe in air, which is a mix of many different types of gasses. Our body absorbs the oxygen from the air, and expels any gasses that our body will not use.
All animals breathe out the same gases. It's a fact of Respiration.
The difference - is in the proportion of the gasses present. The air we breathe in contains about 20% Oxygen. What we breathe out has about 16% oxygen and high levels of carbon dioxide.
78% of the air we breathe is nitrogen. 21% is oxygen, and the other 1% is a mix of other gasses.
