Oxygen forms about 21% of the air around us. In your body, oxygen forms a vital role in the production of energy in most cells. But if gases can only efficiently diffuse across tiny distances, how does oxygen reach the cells deep inside your body? Enda Butler tracks the surprisingly complex journey of oxygen through your body. \[Directed by Dalibor Rajninger, narrated by Addison Anderson, music by Alexander Daniel, Alexander Evtimov, Mihail Yosifov\].
