How much of the oxygen in the air that I breathe in is absorbed by my lungs? If the air I breathe in contains 19% oxygen, what is the composition of the air I exhale? Also, I am a runner, and as I get into shape, I can run faster and faster. Is this because my lungs are taking more oxygen out of the air I breathe? Or is it because I am able to breathe in more air per breath? Or more breaths per minute? Or are my leg muscles able to do more work with the same amount of oxygen?
