What happens after oxygen leaves the blood to move into cells of the body?

As oxygen leaves the blood and enters body cells, carbon dioxide from the cells enters the blood; some of it binds to hemoglobin. The blood then carries carbon dioxide to the lungs, where it moves into the lungs and is exhaled. So “Carbon dioxide binds with hemoglobin,” “Carbon dioxide moves back into the lungs,” and “Carbon dioxide is exhaled from the body” apply; the blood is not low in carbon dioxide.
