Oxygen diffuses into cells. Carbon dioxide diffuses out.
Carbon dioxide is the atmospheric gas expelled by body cells. It is produced during cellular respiration and is then exhaled out of the body through the lungs.
Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.
The blood carries oxygen to all the cells of the body.
The gas that you exhale is called carbon dioxide. It is produced as a waste product of cellular respiration in your body's cells.
Oxygen! Remember it isn't the only gas. CO2 is also removed from cells in the body.
In gas cans.
Blood moves Carbon Dioxide, or CO2, away from body cells through the Circulatory system. It is taken to the lungs, diffused into alveoli, and then is exhaled. CO2 is the waste product of cellular respiration, which is the process that mitochondria use to create usable cellular energy.

Oxygen and carbon dioxide move into and out of cells through diffusion. Oxygen diffuses into cells to be used in cellular respiration, while carbon dioxide diffuses out of cells as a waste product of this process.
