Vote for this answer. I'd assume that the amount of each element we breathe in would be similar to the amount in which they are present in our atmosphere, which would mean 78% of it is nitrogen, 21% is oxygen, 0.9% is argon, and so on... When we exhale, however, we probably let out a lot less molecular oxygen and a lot more carbon dioxide (in the form of carbon + oxygen).
There are about 300 million alveoli in a normal lung. When the air that you've just breathed in reaches these air sacs, the oxygen in the air passes through the air sac walls into the blood in the capillaries.At the same time, carbon dioxide (a waste gas) moves from the capillaries into the air sacs.This process is called gas exchange. The oxygen-rich blood in the capillaries then flows into larger veins, which carry it to the heart.here are about 300 million alveoli in a normal lung.
