This is what happened in F.ukushima, Japan, in 2011, after a series of devastating earthquakes and tsunamis. This is why F.ukushima is still experiencing extremely high levels of radiation and parts of that area cannot be inhabited anymore.

Describe what happens to the air in the lungs when we breathe. What happens to the concentration of
Otrada [13]

When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.

Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.

Hope this helped, even if it helped a tiny bit. :)
