Oxygen dissociation curve byjus

WebAn oxygen–hemoglobin dissociation curve is a graph that describes the relationship of partial pressure to the binding of oxygen to heme and its subsequent dissociation from heme (Figure 2). Remember that gases travel from an area of higher partial pressure to an area of lower partial pressure. WebAug 1, 2024 · Hemoglobin carries 98% of the oxygen in the blood in the protein-bound form, approximately 197 ml/L. It is important to differentiate between pO2 (mm Hg, the dissolved fraction), oxygen saturation (% of hemoglobin occupied), and O2 content (expressed as a volume percentage). Arterial oxygen content is approximately 20 g/dL, the venous oxygen ...
