The Rh factor is important when we learn about the Rh blood group system.

当我们了解Rh血型系统时，Rh因子是很重要的。

However, in the Rh blood group system, the antibodies are not automatically produced.

然而，在Rh血型系统中，抗体并不是自动产生的。

But, as the name implies, the Rhnull blood type is completely missing these Rh blood group antigens, which makes it the rarest blood type in the world.

但是，正如该血型名字所暗示的那样，Rhnull血型便没有这些Rh血型抗原，这使它成为世界上最罕见的血型。

It's almost like her body doesn't even care which Rh blood group she belongs to.

就好像她的身体根本不在乎她属于哪个Rh血型。

The Rh blood group system is a classification system for blood that depends on the presence or absence of the Rh antigen - or factor - on your red blood cells.

Rh血型系统是一个血液分类系统，取决于红细胞上Rh抗原或因子存在与否。

So you might think that the Rh blood group would be the same way and assume that if you are born without the Rh antigen that your body would automatically make antibodies against it.

所以你可能会认为Rh血型是相同的，并假设如果你出生时没有Rh抗原，你的身体会自动产生抗体。
