The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygenenters the lungs and reaches the alveoli. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.

How does oxygen concentration change with relation to carbon dioxide?

Oxygen concentration tends to decrease as carbon dioxide levels increase. This is due to the fact that high carbon dioxide levels can displace oxygen in the air, leading to lower oxygen concentrations. Therefore, there is an inverse relationship between oxygen and carbon dioxide concentrations in the atmosphere.

Why do the totals of carbon dioxide and oxygen not change?

i don't completely under stand your question, but if you're asking why the amount of it in the air doesn't change, the answer is simple. we breathe in oxygen and let out carbon dioxide. while plants "breathe in" carbon dioxide and let out oxygen. oxygen is also made from chemical reactions from the ocean. but this is not enough to supply this much life with oxygen, and we still don't know where all the extra oxygen came from.
