If you do not breathe the blood in your veins and arteries can not flow. The exchange of CO2 and oxygenated blood can not mix and exchange in the heart. The gas from CO2 will suffocate you and you will die.
Immediately. You need lungs to breathe; without the ability to breathe, you will die.
If you didn't breathe while you slept, you would die of suffocation.
People breathe out because we need to breathe fresh air, and if we kept the same air in our bodies it would not be fresh after a while, and we would die.
Because they can breathe through their skin and when it dries out, they would not be able to breathe.
because if they didn't they would die. :(
Yes. We breathe air all the time. If we didn't we would asphyxiate and die.
You would suffocate, have brain damage, and die.
No you would die suffocating from that
One reason is cuz u need it to breathe its photosythesis. We breathe out carbon dioxide plants breathe that in and breathe out oxygen which we breathe in. Without plants we would die.
We would all die because without it we would have no air to breathe.
if you didn't have them you wouldn't be able to breathe and then you would die
Yes, but you would die for sure. The combustion reaction would take all the oxigen and you will breathe carbon dioxide/carbon monoxide and that would kill you.
