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 22.26 ). Remember that gases travel from an area of higher partial pressure to an area of lower partial pressure.
