How do the heart and lungs work?

When we breathe in our lungs fill with oxygen rich air. Membranes in the lungs exchange the oxygen from the air with carbon dioxide in the blood. Then we breathe out the spent air to inhale fresh. The blood, now replenished with oxygen, is pumped by the heart through the arteries to all cells in the body where the oxygen is exchanged with the cells for carbon dioxide and returned through the veins to the lungs.
