Vote for this answer. I'd assume that the amount of each element we breathe in would be similar to the amount in which they are present in our atmosphere, which would mean 78% of it is nitrogen, 21% is oxygen, 0.9% is argon, and so on... When we exhale, however, we probably let out a lot less molecular oxygen and a lot more carbon dioxide (in the form of carbon + oxygen).
Humans need oxygen to live, but not as much as you might think. The minimum oxygen concentration in the air required for human breathing is 19.5 percent. The human body takes the oxygen breathed in from the lungs and transports it to the other parts of the body via the body's red blood cells. Each cell uses and requires oxygen to thrive. Most of the time, the air in the atmosphere contains the proper amount of oxygen for safe breathing.
