Oxygen in the atmosphere is breathed in by oxygen-breathing organisms (such as humans) which convert it into Carbon Dioxide. To go one step further, the CO2 is used by plants to make glucose; a process which releases oxygen as a biproduct.
At any rate, Oxygen is inhaled into the lungs, which enable the O2 to be absorbed into the bloodstream. Blood cells then use the oxygen in a chemical process to create ATP (energy), and through that process Carbon Dioxide is a biproduct. Thus, the blood takes the CO2 back to the lungs, where it is exhaled back into the atmosphere.
