WebHb is a red blood cell protein that plays an essential role in sustaining aerobic metabolism by transporting O 2 from the respiratory exchange surfaces (e.g., lungs, gills, or skin), where the partial pressure of O 2 (PO 2) is high, to the cells of respiring tissues, where the PO 2 is low and the partial pressure of CO 2 (PCO 2) is elevated by metabolic activity. WebIn the lungs, oxygen diffuses from the air in alveoli into the blood of surrounding capillaries. Most of the oxygen enters RBCs and combines with the heme portions of hemoglobin (Hb) to form oxyhemoglobin (HbO 2 ). About 98.5% of the oxygen is transported as oxyhemoglobin. The remaining 1.5% is dissolved in the plasma.
