Human blood groups, Rh system #280675907
Description
The Rh blood group system is one of the most well-known blood group systems in humans. It is based on the presence or absence of the Rh antigen on the surface of red blood cells. Individuals who have the Rh antigen are classified as Rh-positive (Rh+), while those who lack the Rh antigen are classified as Rh-negative (Rh-). The Rh system is crucial in blood transfusions and pregnancy, as Rh incompatibility between a Rh-negative mother and a Rh-positive fetus can lead to complications.
