What is the body organ which oxygen passes through to capillaries?

The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.


What organ allows oxygen that passes from them into capilleries?

Where does the body get its oxygen from?

Human bodies take air into the lungs and remove oxygen from it (air is about 21% oxygen). In the alveoli (air sacs within the lungs) oxygen passes into the bloodstream where it is absorbed by the chemical hemoglobin in red blood cells. The oxygen is carried to all the cells of the body. The blood cells pick up carbon dioxide that the cells create when they oxidize food to get energy. This carbon dioxide is returned to the lungs, where it leaves the blood and is released from the body when you exhale.

What passes oxygen from the air to the blood?

Oxygen is passed from the air to the blood through the process of diffusion in the alveoli of the lungs. The alveoli are surrounded by tiny blood vessels called capillaries, where oxygen diffuses into the bloodstream and carbon dioxide diffuses out of the bloodstream to be exhaled.


What two arteries bring the blood to the lungs for oxygen?
