Answer 2

It asks about oxygen. When oxygen enters the body it goes to one organ in particular. There it diffuses into the blood. The now oxygen laden blood goes back to the heart and from there the heart pumps it out to the rest of the body.

If you answer "which organ" you will own this question.
