Definition
Human blood groups refer to the classification of blood based on the presence or absence of specific antigens on the surface of red blood cells, primarily categorized into the ABO system (A, B, AB, and O). The Rh factor is a separate antigen that can be present (Rh-positive) or absent (Rh-negative) on the surface of red blood cells, influencing blood compatibility in transfusions and pregnancy.
Summary
Human blood groups are essential for understanding how blood transfusions and organ transplants work. The ABO system and the Rh factor are the two main classifications that determine compatibility. Knowing your blood type can save lives in emergencies and is crucial for safe medical practices. Blood types are inherited genetically, and their significance extends beyond transfusions to areas like paternity testing and genetic research. Understanding blood groups helps us appreciate the complexity of human biology and the importance of safe medical procedures.
