The ABO system is a classification system for the different blood types in humans. It is based on the presence or absence of certain proteins on the surface of red blood cells. This system is important in medical transfusions and transplants, as it helps to determine which blood types are compatible with each other.
Definitions
The ABO system is a classification system for blood types based on the presence or absence of certain proteins on the surface of red blood cells. There are four main blood types in the ABO system: A, B, AB, and O.
Origin
The ABO system was first discovered by Karl Landsteiner, an Austrian immunologist, in 1900. He found that mixing the blood of different people could cause it to clump together, which led him to identify the different blood types.

The Oxford English Dictionary defines it as “a system of classification of human blood based on the presence or absence of antigens A and B on the surface of red blood cells.”.
