If you are referring to the cetacean, they expell stale air containing carbon dioxide from their blowhole.
If you are referring to the mahi-mahi (common dolphinfish) or pompano dolphinfish, they exchange carbon dioxide for oxygen in their gills by pulling oxygen-rich water through their mouths and pumping it over their gills.
Dolphins breathe through the 'blow hole' in the top of their heads, surfacing from underwater to blow out the Carbon Dioxide and draw in oxygen.
All animals breathe one way or another, to get oxygen carbon dioxide out. It's that or die.
when you breathe in, you breathe in oxygen and when you breathe out, its carbon dioxide
It is only carbon dioxide. That is all you breathe out.
We breathe in oxygen and breathe out carbon dioxide. Plants take in this carbon dioxide and release oxygen, which we use after that.
For We can Breath In Carbon Dioxide. :)We do not breathe in carbon dioxide (CO2), we actually breathe in oxygen, and let out carbon dioxide, which trees use to breathe.
It is possible to breathe in carbon dioxide because if you smoke, you will breathe in carbon dioxide.
trees breathe out oxygen we breathe out carbon dioxide and trees breathe in carbon dioxide SAVE THE RAINFORESTS OR WE'LL DIE!!
Penguins breathe in oxygen and breathe out carbon dioxide. They have this in common with all animals.
Respiration creates carbon dioxide through breathing out. When we inhale, we breathe in oxygen, when we breathe out, it's released as carbon dioxide.
Plants breathe in carbon dioxide and breathe out oxygen; animals breathe in oxygen & breathe out carbon dioxide.
Well plants breathe in Carbon Dioxide and breathe out Oxygen. We breathe in the oxygen and breathe out Carbon Dioxide. So its like a cycle.
