Both! your body only keeps the oxygen though and when you breath out the carbon ddioxide comes out
when you inhale you breath oxygen when you exhale carbon dioxide
Animals exhale carbon dioxide and inhale oxygen just as humans do.
plants inhale carbon dioxide and breath out oxygen. Its the opposite of what humans do, we breathe in oxygen and breathe out carbon dioxide.
When we inhale through the nose, we breathe in oxygen and some carbon dioxide. When we exhale, there is more carbon dioxide than oxygen. This is because the oxygen is absorbed and converted by the lungs into carbon dioxide.
You don't only "breath in air, and breath out air," You breath in Oxygen and let out Carbon Dioxide. Passes to the diaphragm and the lungs, inhale oxygen, it goes through your body, exhale Carbon Dioxide, From which the body has made when inhaled.
Nope -- they do just exactly the opposite: inhale and use oxygen, and exhale more carbon dioxide, just as all mammals do. This was an old wive's tale that's been around for years, that goes on to say cats can suck away a baby's breath -- which has no basis in fact whatsoever.
It goes through your respiratory system, and into the blood stream, where the oxygen takes the place of 'old oxygen', which has been converted to carbon dioxide, and you breath out the carbon dioxide. That is repeated with each breath.
You inhale oxygen and exhale carbon dioxide, and plants produce oxygen using carbon dioxide, called photosynthesis.
All of the air in the lungs gets exchanged with oxygen upon each breath. We exhale carbon dioxide and inhale oxygen.
you breath in as you inhale breath out is exhale
Oxygen
Humans inhale oxygen, and breath out carbon dioxide. It is like a cycle.
