Which systems work together so oxygen can be distributed to the cells of the body?

How do these two systems work together to accomplish this tasks?

The sample response:

The respiratory and the circulatory systems work together to bring oxygen to the cells in the body. The respiratory system takes oxygen from the air to the lungs, where the oxygen is transferred to the blood. The circulatory system transports the blood, which delivers oxygen to the cells in the body.

The human respiratory and circulatory systems work together to supply the body with oxygen and get rid of waste carbon dioxide. The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Hope that makes sense
