The<unk> , also called the oxyhemoglobin<unk><unk>  or oxygen<unk><unk>  (ODC), is a<unk>  that plots the proportion of<unk>  in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis. This<unk>  is an important tool for understanding how our blood carries and releases oxygen. Specifically, the oxyhemoglobin<unk><unk>  relates oxygen saturation (SO2) and partial pressure of oxygen in the blood (PO2), and is determined by what is called<unk>  affinity for oxygen"; that is, how readily<unk>  acquires and releases oxygen molecules into the fluid that surrounds it.
