BLOOD GROUPS Meaning and
Definition
-
Blood groups refer to the classification system used to categorize human blood based on the presence or absence of specific antigens on the surface of red blood cells (RBCs). These antigens, also known as agglutinogens, represent unique markers that determine an individual's blood type.
The most well-known blood group system is the ABO system, which classifies blood into four main types: Type A, Type B, Type AB, and Type O. Antigens A and B are the primary markers in this system. Individuals with Type A blood carry antigen A on their RBCs, Type B individuals carry antigen B, while those with Type AB blood have both antigens. Conversely, individuals with Type O blood possess neither antigen A nor antigen B.
In addition to the ABO system, the Rh (Rhesus) system is another important blood group classification. This system categorizes blood as either Rh-positive or Rh-negative, based on the presence or absence of the Rh antigen. Rh-positive individuals possess this antigen, while Rh-negative individuals lack it.
Understanding blood groups is crucial in medical and transfusion contexts. It helps determine compatibility between blood donors and recipients during blood transfusions and organ transplants. Blood types should be matched to avoid adverse transfusion reactions, where the immune system of the recipient reacts against the foreign blood cells. RBCs with antigens matching those of the recipient are considered compatible, while those with non-matching antigens are considered incompatible.
Overall, blood groups provide a comprehensive framework for understanding the diverse variations and compatibility of human blood, enabling safe transfusions and medical interventions.

Etymology of BLOOD GROUPS
The word "blood groups" is a compound term that combines the words "blood" and "groups". Let's break down the etymology of each component:
1. Blood: The word "blood" comes from the Old English word "blōd", which can be traced back to the Proto-Germanic word "*blōþam". This source ultimately has uncertain origins, but it is thought to be related to the Proto-Indo-European root "*bhlo-", meaning "to thrive, bloom". The term "blood" refers to the red liquid that circulates in the veins and carries nutrients, oxygen, waste products, hormones, and other vital substances throughout the body.
2. Groups: The word "groups" is derived from the Middle English word "group", which was borrowed from the Old French term "groupe".
