Why do we Only inhale oxygen?
Yk what all the basic science books say, "we inhale oxygen and exhale carbon dioxide". But like according to what I know, our surroundings are filled with so many gasses besides just oxygen. So why do we SPECIFICALLY breath only oxygen? I don't see my nose hole having a filter in front of it. 🗿
