When we breathe in the intercostal muscles in the rib cage contract and the chest inflates, while filling up with air, at this point the diaphragm flattens. The oxygen then goes down the trachea and through the bronchiole tubes and into the lungs, where it meets the alveoli. The Oxygen in the alveoli then diffuses through the alveoli and through the capillaries in the lungs. The capillaries are only one cell thick, thus making it easier for the oxygen and carbon dioxide to diffuse through. The carbon dioxide diffuses through, in the other direction from, the capillaries to the alveoli, where it can leave the body via the bronchiole tubes, trachea and exiting out the mouth. When we breath out, the diaphragm relaxes and goes back into the dome shape, the intercostal muscles also relax, allowing the chest to deflate.

Also there is most likely a type of living thing which no human has ever discovered and so there may be milllions of kind of living things that may not breathe in oxygen - they might not even breathe in a gas!
Why is carbon dioxide released when you breath?
its called photosynthesis trees let out oxygen and you breathe it in then you breathe out carbon dioxide which the trees breathe in. So basically its from the oxygen the trees breathe out
