Does oxygen come out of your tissue and go to your lunges or does carbine dioxide come out of your tissues and go to your lunges?

Carbon dioxide is released from your tissues into the bloodstream, where it is transported to the lungs for exhalation. Conversely, oxygen moves from the lungs into the bloodstream and is delivered to the tissues for cellular respiration. Essentially, oxygen goes from the lungs to the tissues, while carbon dioxide travels from the tissues to the lungs.
