down through the trachea and after goes to the bronchial tubes and into the lungs.
Finally, oxygen goes to our blood. When we breathe, we can differentiate two movements:
inhalation, our lungs fill with air, we take oxygen from the atmosphere and expiration,
air leaves our lungs, giving off carbon dioxide.
