Answer:Blood Type is a classification for some of the proteins (antigens) found on the red blood cells our bodies make. People who have "type A" blood also produce "Type A" antigens AND produce "Anti blood type B" antibodies.

Same goes for someone who has blood "type B". They produce "Type B" antigens and produce "Anti blood type A" antibodies.

When a person receives the 'wrong blood type' what is happening is that the persons own "Anti blood type antibodies" are attacking the new red blood cells because the new red blood cells have the protein saying they are "A" or they are "B" all over them.

People who have blood type "AB" make BOTH antigen proteins on their red blood cells and they dont produce either of the 'anti blood type antibodies'. Since there are no antibodies there is nothing to fight with the red blood cells protein markers (aka antigens) so they do not have a bad reaction. They can get blood from anyone.

Blood type O is not like blood type A or B and its even different than blood type "AB".

The "O" means "Other". Even though the type of antigen protein their red blood cells have is 'other' than "A" or "B" they still produce the 'anti a' and the 'anti b' antibodies.

So they should only ever receive blood from other "blood type O" donors.

If you want to know how these types (and others) evolved, see Scientific American in the related link below.

What are the different types of Russian blood types, and how do they differ from blood types 1, 2, 3, and 4?

There are four main blood types in Russia: A, B, AB, and O. These types are similar to the blood types 1, 2, 3, and 4 commonly used in other countries. The main difference lies in the specific antigens present on the red blood cells, which determine compatibility for blood transfusions.


What are the common European blood types and how do they differ from blood types found in other populations?

Common blood types in Europe are A, B, AB, and O. These blood types are also found in other populations, but the distribution may vary. For example, the O blood type is more common in European populations compared to some other regions. Additionally, the Rh factor, which determines positive or negative blood types, is also present in European populations.


Is all human blood same?

No, all human blood is not the same. Blood types are determined by the presence or absence of certain antigens on the surface of red blood cells, with the most common blood types being A, B, AB, and O. Additionally, blood can also differ in terms of Rh factor, which further classifies blood as Rh positive or Rh negative.


Which blood types can blood type A receive a transfusion from during a transfusion, considering that blood type A can receive from blood types A and AB?

Blood type A can receive a transfusion from blood types A and AB.


Do you think there are as many blood types as there are letters in the alphabet?

No, there are four primary blood types: A, B, AB, and O. Each of these blood types can be either positive or negative, making a total of eight possible blood type combinations. These blood types are determined by the presence or absence of certain antigens on the surface of red blood cells.

Are there three types of blood cells - red blood cells and white blood cells and blue blood cells?

No. There are no blue blood cells. There are only white blood cells (lymphocytes) and red blood cells(erythrocytes).
