From what we know, we can confirm that after inhalation into the lungs, oxygen gas is more concentrated in the alveoli and diffuses into the blood.
<h3>Why does this happen?</h3>
The alveoli are the primary place for the interchanging of gases to take place. This means that oxygen enters the lungs and makes its way into the alveoli, where it diffuses into the bloodstream in exchange for <u>carbon dioxide </u>that is later expelled from the body during <u>exhalation</u>.
