Answer: To bring oxygen into the body and to remove carbon dioxide from the body.

Explanation: For me it's obvious to know that it's to bring oxygen, is because if you don't know, respire means to breathe, and the lungs are part of the respiratory system. To bring oxygen into the body and to remove carbon dioxide from the body.
