How oxygen is being transported?
About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.
