So it's going to be obviously oxygen XD ....so that's one

Next, it's going to be carbon dioxide, since it has to exit the cell, because it is a waste product ...so that's two

Finally, it's also going to be something you drink everyday.

*whispers* it's water XD because of osmosis


So recap:

1) Oxygen 2) Carbon Dioxide 3) Water


hope that helps!! :D
