Once blооd аrrives аt the tissue, the аmоunt of oxygen that will be delivered/unloaded from the red blood cells is based on the tissue's metabolism. List two factors in the tissue that will increase the delivery of oxygen (via oxygen unbinding from hemoglobin, not by increasing flow) in response to a higher metabolic rate.
