Simply put, you are A, B, AB or O depending on if you have A antigens, B antigens, both antigens or neither of the antigens.

简单的来说，根据你的抗原是A型、B型、AB型，还是没有抗原而将你区分成A型血、B型血、AB型血和O型血。

If you have A antigens, it’ll clump with A antibodies.

如果您有 A 抗原，它会与 A 抗体结块。

If you have type A, that means your red blood cells have the A antigens.

如果您是 A 型，则意味着您的红细胞具有 A 抗原。

For example, if you have type B blood and you receive a blood transfusion of type A blood, your antibodies will work to destroy the A antigens.

例如，如果你是B型血，却输了A型血，你的抗体就会破坏A型血抗原。

For example, if your red blood cells have A antigens, then you will have type A blood.

例如，如果您的红细胞含有A抗原，那么您将拥有A型血液。

So the name of your blood type refers to what kind you have or don't have: A-type has A antigens, B-type has B, AB has both, and O has neither.

所以你的血型的名字是指你有或没有什么样的血型：A 型有 A 抗原，B 型有 B 抗原，AB 型有这两种抗原，O 型两者都没有。

However, your immune system would not be familiar with A antigens because they are not present on your red blood cells.

然而，免疫系统并不熟悉抗原，因为它们不存在于红细胞上。

Therefore, if you have type A antigens stuck on the outside of your red blood cells, you will develop only anti-B antibodies.

因此，如果您的红细胞外部粘附有A型抗原，则只会产生抗B抗体。

Your body would form antibodies against A antigens, called anti-A antibodies, and this mixing could lead to clumping or agglutination of the blood.

身体会形成对抗抗原的抗体，称为抗-A抗体，这种混合可能导致血液凝结或凝集。

If you have type A blood, your red blood cells have the A antigen, and your body will produce anti B-antibodies.

如果是A型血，红细胞有A抗原，身体会产生抗B抗体。

The Rh factor is simply a red blood cell antigen - just like the A antigen and the B antigen that are used to determine your blood type.

Rh因子只是一种红细胞抗原，就像用来确定血型的A抗原和B抗原一样。

This is a very good thing, if you think about it, because if you had type A antigens on your red blood cells, and your body formed anti-A antibodies, they would destroy your own blood.

思考，这是一件非常好的事情，因为如果您的红细胞上有A型抗原，并且您的身体形成了抗A抗体，它们会破坏您自己的血液。
