Blood is a vital component of the human body, and it plays a crucial role in the transportation of oxygen and nutrients to various parts of the body. The ABO blood group is one of the most well-known blood groups, and it is essential in determining blood compatibility for transfusion purposes. In this article, we will explore the definition and meaning of the ABO blood group.
Definitions
The ABO blood group is a classification system for human blood based on the presence or absence of antigens A and B on the surface of red blood cells. There are four main blood types in the ABO blood group: A, B, AB, and O. Blood type A has antigen A on the surface of red blood cells, blood type B has antigen B, blood type AB has both antigens A and B, and blood type O has neither antigen A nor B.
Origin
The ABO blood group was discovered by Karl Landsteiner, an Austrian biologist, in 1901. He was awarded the Nobel Prize in Physiology or Medicine in 1930 for his discovery. Landsteiner found that when he mixed blood from different individuals, some combinations caused the blood to clump together, while others did not. He identified the ABO blood group system based on the clumping reactions.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, the ABO blood group is “a classification system for human blood based on the presence or absence of antigens A and B on the surface of red blood cells.” 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.”
Associations
The ABO blood group is associated with various medical conditions and traits. For example, people with blood type A have a higher risk of developing stomach cancer, while people with blood type O have a lower risk. Blood type also affects the risk of developing certain infections, such as malaria and cholera. Additionally, blood type can affect fertility and pregnancy outcomes.
