WebJan 17, 2024 · This curve shows the saturation of oxygen bound to hemoglobin compared to the partial pressure of oxygen (concentration) in blood. Oxygen saturation curve: Due to cooperative binding, the oxygen saturation curve is S-shaped. pH Control RBCs control blood pH by changing the form of carbon dioxide within the blood. WebThe oxygen dissociation curve is a graph with oxygen partial pressure along the horizontal axis and oxygen saturation on the vertical axis, which shows an S-shaped relationship. Oxygen and carbon dioxide are transported in the blood as a result of changes in blood partial pressures ( Figure 5.1 ).
