What happens to gases you inhale?

Answer 1

According to wikipedia's article on the composite of gasses which we breathe every day (Air): It contains roughly (by molar content/volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, trace amounts of other gases, and a variable amount (average around 1%) of water vapor.

Answer 2

once gas is inhaled it goes threw the blood stream were cells take the molecules bring them to the lungs and the lung exhale releasing the gas molecules from the body however in large quantity's the gas is to much to exhale and can cause death.

Answer 3

We inhale air, which is about 78% Nitrogen, 20% Oxygen and 1% Argon. The air usually has some humidity in it so we probably inhale some water vapor as well. We exhale pretty much all of the Nitrogen and Argon, but some of the Oxygen is replaced with Carbon Dioxide. We also usually add some water vapor to it,

so:

Inhale: Nitrogen, Oxygen, Argon, Water (vapor)

Exhale

Nitrogen, Oxygen, Carbon Dioxide, Argon, Water (vapor)
