Web3 jan. 2024 · Hemoglobin is an iron-rich protein in red blood cells that helps to transport oxygen throughout the body. High hemoglobin levels could be due to polycythemia. WebThe first mechanism of carbon dioxide transport is by blood plasma, as some carbon dioxide molecules dissolve in the blood. The second mechanism is transport in the form of bicarbonate (HCO 3– ), which also dissolves in plasma. The third mechanism of carbon dioxide transport is similar to the transport of oxygen by erythrocytes ( Figure 22.5.4 ).
