carbon dioxide
Oxygen is the gas that passes from the bloodstream to body cells through the process of oxygenation. Oxygen is essential for cellular respiration, which is the process that cells use to generate energy.
oxygen
The blood carries oxygen to all the cells of the body.
Blood picks up oxygen in the lungs when it passes through the alveoli, tiny air sacs where gas exchange occurs. Oxygen from the air we breathe enters the blood in the lungs and is then carried throughout the body by red blood cells.

Oxygen (O2)
Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.
Oxygen! Remember it isn't the only gas. CO2 is also removed from cells in the body.
carbon dioxide
Blood loses oxygen as it passes through the capillaries in the body's tissues. Oxygen is delivered to the tissues by red blood cells, which release oxygen molecules into the surrounding cells for cellular respiration. This process occurs in various organs and tissues throughout the body, allowing cells to produce energy for their functions.
The gas exchange between the blood and the cells of the body is an example of cellular respiration. During cellular respiration, cells use oxygen from the blood to produce energy, releasing carbon dioxide as a waste product, which is then carried back to the lungs by the blood for elimination.
