The oxygen-hemoglobin saturation curve illustrates the effect of increasing PO2 on the percent saturation of hemoglobin with oxygen.

氧合血红蛋白饱和度曲线说明了增加PO2对氧合血红蛋白饱和度的影响。

Let's take a look at what we call the oxygen-hemoglobin saturation curve, and this will help illustrate how cooperative binding helps transport oxygen in our body.

我们来看看所谓的血氧饱和度曲线，这将有助于说明协同结合如何帮助我们体内的氧气运输的。
