How do the circulatory system and the respiratory system function together in the body? 1) The circulatory system carries carbon dioxide away from cells to be exhaled by the respiratory system and exchanges it with oxygen from the lungs to be carried back to the cells.
2)The circulatory system carries nitrogen away from cells to be exhaled by the respiratory system and exchanges it with sulfur dioxide from the lungs to be carried back to the cells.
