I know that there is A B AB and O but like what is the difference between each type? What is the point of each blood type? Why are there even different types? Thanks

Human blood is grouped into four types: A, B, AB, and O. Each letter refers to a kind of antigen, or protein, on the surface of red blood cells. For example, the surface of red blood cells in Type A blood has antigens known as A-antigens.
The Rh Factor
Each blood type is also grouped by its Rhesus factor, or Rh factor. Blood is either Rh positive (Rh+) or Rh negative (Rh-). About 85% of Americans have Rh+ blood.
Rhesus refers to another type of antigen, or protein, on the surface of red blood cells. The name Rhesus comes from Rhesus monkeys, in which the protein was discovered.

There are different types identified because if you mix the wrong blood groups together as in a blood transfusion a person will die. The different groups and the positive and negative identify which blood types must not be mixed because they will clot and cause death. Type 'O' is considered a universal donor because it can be mixed with other blood types. Type AB is the rarest and can only be used with type AB blood as it will clot with the others. Positive and negative blood also cannot be mixed. Some babies are born who must have their blood exchanged for a different type at birth because of the positive/negative factors between the mother and infant.

There are 3 types of antygens one is A, one is B and the other is Rh and showed with + or -. If you are A you have only A antigen, and that means you have B antibody. If B antibody and B antigen gets together you die. That means 0 cant get any blood from any blood types but 0 because it has both antibodies and AB can get blood from every type because it doesnt hve antibodies. Rh has nothing to do with A and B antigens. If there is Rh in your blood, I mean if you are Rh+ that means you can get blood from both Rh+ and Rh- blood types. But if you have Rh- then that means you have Rh antibody and you can't take blood from Rh+. - can give because it doesn't contain any antigens. Thant means 0- can give everyone blood but only take 0- blood and AB+ can take every kind of blood but only give AB+ blood. That is why doctors say 0- is the hardest blood to find.

ABO are antigens on red cells. They are significant because you make antibodies to the ABO antigens you dont have. This comes into play if you have to have a transfusion (if you are given an antigen you lack your body will attack those cells). Type A have anti-B. Type B have anti-A. Type AB do not have anti-A or anti-B (so they can recieve red cells from any ABO type). Type O has anti-A and anti-B and anti-A,B (but do not have A or B antigens so they can give to any type) I hope that made sense
