Carbon dioxide diffuses out of cells into the bloodstream and is transported to the lungs to be exhaled. Oxygen is taken up by red blood cells in the lungs and transported to cells where it diffuses into the cells to be used for energy production.
Oxygen moves through the body via the bloodstream, carried by red blood cells. It is inhaled into the lungs, where it diffuses from the alveoli into the bloodstream, and then transported to tissues and organs where it is exchanged for carbon dioxide to be exhaled.
Stomata.
Oxygen and carbon dioxide move in and out of a leaf through tiny openings called stomata. Stomata are located on the underside of the leaf and allow for gas exchange between the leaf and the surrounding atmosphere.
Oxygen moves from the alveoli into the bloodstream through diffusion, where it crosses the thin walls of the alveoli and capillaries. Similarly, carbon dioxide moves from the bloodstream into the alveoli for removal when blood with high levels of carbon dioxide comes into contact with alveolar air with lower levels of carbon dioxide.
Oxygen and carbon move through the environment primarily through the processes of photosynthesis and respiration. During photosynthesis, plants take in carbon dioxide and release oxygen, while during respiration, organisms take in oxygen and release carbon dioxide. This cycle helps to maintain a balance of these two essential elements in the environment.
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.
Oxygen enters cells through diffusion, where it moves from areas of high concentration in the bloodstream to low concentration in cells. Carbon dioxide exits cells through the same process, diffusing from high concentration in cells to low concentration in the bloodstream for removal by the lungs.
Guard cells control the size of openings (stomata) that allow carbon dioxide and oxygen to move into and out of a leaf. Guard cells change shape to open or close the stomata in response to environmental conditions like light intensity, humidity, and carbon dioxide levels.

Oxygen moves into our bodies by diffusion, while carbon dioxide moves out of our bodies by the same process. Oxygen is taken in by our cells for cellular respiration, while carbon dioxide is the waste product produced by this process and is expelled from the body.
The alveoli are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged. They are thin-walled, and closely associated with the thin-walled capillaries that surround them. Oxygen and carbon dioxide diffuse across these thin walls to move from the blood to the lungs.
