Oxygen in, Carbon Dioxide out.
Another answer
Breathing breathes in the atmosphere: not the whole atmosphere obviously, but its composition. Breathing in occurs because of the necessity of oxygen-entrance and breathing out occurs because of the necessity of carbon dioxide-exit.
The air consists of 79% nitrogen and 21% oxygen and 0.04% carbon dioxide and equally tiny percentages of other gases. We breathe in this 79% nitrogen and breathe out an equal percentage. We breathe in 21% oxygen and breathe out 16% oxygen. We breathe in 0.04% carbon dioxide and breathe out 4-5% carbon dioxide.
you brethe in everything in the air but your lungs filter out the bad stuff and keep the oxygen and everything else is brethed out
air
Oxygen and carbon dioxide
its what you breathe and what plants breathe out while they breathe that out they breathe in carbon diOxide and we breathe it out.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
Humans breathe out carbon dioxide, the whole world runs in a motion, for example plants breathe carbon dioxide, we breathe in oxygen. Even fish breathe oxygen. They take the oxygen out of the water. So we breathe in what plants breathe out and plants breathe in what we breathe out.

"Breathe in and breathe out, for you must breathe to live."
You breathe out more water vapour then when you breathe in
Plants breathe Co2 and we breathe Oxygen.
You do breathe when you sleep. Everyday you breathe so you don't always "sleep when you breathe".
when you breathe out, plants breathe in.
We breathe in oxygen and breathe out carbon dioxide.
Yes, we breathe germs in, and we breathe our own germs out.
Carbon Dioxide. Actually you breathe in 78% Nitrogen so... Breathe in is to all sorts of gases.
