The Mitochondria
Mitochondria are sometimes called the "powerhouses" of the cell. The energy is released by combining food with oxygen, in a process called aerobic respiration. The oxygen from the food is needed to help the cell move and grow.
Oxygen is used to produce ATP in the mitochondria, which powers our cells to do its functions.
The lungs, as blood passes through the lungs, they deposit carbon and receive oxygen.
As blood passes through lungs, there is exchange of oxygen and carbon bi oxide, from high concentration to low concentration and oxygen enters the blood from air to blood to make it oxygen rich.

alveoli
Oxygen passes from the blood into organs through the wall of capillaries.
blood take oxygen from blood.

the blood is given oxygen as it passes next to the alveoli in the lungs. The process by which the blood gets oxygen is called diffusion

Blood and oxygen.

Oxygen
Blood brings food and oxygen to your cells.
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.
