All bloodtypes10/13/2023 Out the last possibility? Some people have neither A nor B. People would have only the B, and some people, can you figure Might have only the A, or, as you can imagine, some Some people do have both,īut some have only one. Molecules, these glycolipids, on their red blood cells. What's interesting, is that not all people have both of these Glycolipids, glyco meaning a sugar group, lipid meaning a fat group, so it's some kind of They are actually somethingĬalled glycolipids, which I actually didn't realize at first. Molecules and not proteins because they're actually not proteins. Happy with those names, not too hard to remember. We're going to talk about, and those are the A There are two of them that are sort of more important than the others, at least for this topic that Which I'm drawing here, that have all kinds ofĭifferent functions. There's all kinds of proteins and molecules, some of Layer of this red blood cell? Since it's a cell, it has a cell membrane, and that's made up of lipids. Some Rh antigens are more "antigenic" or more likely to cause an immune reaction then others. There are actually hundreds of blood types, and even many Rh antigens. Some things are not as simple as we expect, and transfusion medicine has a lot of interesting details. The amount of antibody will increase with each subsequent Rh+ pregnancy. ![]() With Rh antigen, the first exposure, the Rh negative (Rh-) mother has to be exposed to a Rh+ pregnancy prior to making IgM and then subsequent Rh+ pregnancies will cause IgG to be made, which can cross the placenta and cause hemolysis of the fetal red blood cells. Rh factor is a minor antigen and a person does need exposure to prior to making IgM and then IgG antibodies. So an infant with Type A blood would start producing antibodies against B antigens. The maturing immune system of an infant actually does start making IgM antibodies against the "foreign major antigens" by 2 months of age and does not need a blood transfusion to start that process.
