When some people think of the air we breathe, the first thing that comes to mind is oxygen. While oxygen is the essential component of all breathing gases, the air around us is not pure oxygen.
When you inhale, or breathe in, the air is roughly 78% (by volume) nitrogen, 21% oxygen, 0.96% argon and 0.04% carbon dioxide, helium, water, and other gases.
When you exhale, or breathe out, the air coming out of your lungs is 4% to 5% carbon dioxide and 4% to 5% less oxygen than was inhaled (So, about 16% oxygen). You also breath out about 5% water vapor and other mentioned gases.
If you're wondering why we can't just breath pure oxygen, it's because our reliance on this relatively small amount of oxygen can cause over activity or euphoria in pure or oxygen rich environments.
