Question:
What do we do with the air we breath???
Answers:
I'm not sure I understand just what it is you want to know or how this is related to Dental issues. This is a Respiratory question.
What do we do with it? We inhale air which contains O2. There is a gas exchange at the alveolar level. The blood releases CO2 and picks up O2 from the lungs. We exhale the CO2. And the cycle begins again. If this isn't what you were asking, I'm sorry. Try rewording it and posting it in the Respiratory category.
