ABO SYSTEM OF BLOOD GROUPING • The ABO blood group system was first given by Karl Landsteiner in 1901. Based on the presence of antigen A and B over the surface of RBCs blood groups are classified into four types viz. type A, type B, type AB, and type O. • Type A - In this type, there is antigen A over the surface of RBC and antibody against B in the plasma. • Type B - In this type, there is antigen B present on the surface of RBC and antibody against A in the plasma. • Type AB - In this type, there is both antigen A and B present on the surface of RBC and no antibodies are present in the plasma. • Type O - In this type, there is no antigen present on the surface of the RBC but both antibodies A and B are present in the plasma. • Type AB is a universal acceptor, as it can accept blood from all other types but can donate only to the same group (AB). • Type O is the Universal donor, as it can donate blood to all other groups but can accept only from the same group (O). • RH SYSTEM OF BLOOD GROUPING - DEFINITION • Rh factor is a type of protein present in the blood of some humans. It is also present in Rhesus monkey, hence it is named Rh factor (Rhesus) factor. Presence of Rh factor in an individual is considered as Rh positive whereas the absence of Rh factor is Rh negative. • The blood group of the donor must be compatible with the blood group of the recipient for a safe blood transfusion to take place. • Blood group O is the universal donor and blood AB is the universal recipient.Rh factor plays an important role in blood transfusion. • Rh factor of the donor and the recipient should match with each other. • Blood transfusion between two such individuals will induce high immunogenic response thereby causing the death of the recipient. • #bloodgroups #blood #rhfactor • Subscribe to our channel to watch free online lectures • • For more videos, online classes, 24X7 Doubts solving and Mock tests, Visit Toppr - The better learning app. • #BetterLearning on the Toppr app, download now • Google Play: http://bit.ly/2vRBqcb • App Store: http://apple.co/2vpRAr9 • Website: https://www.toppr.com/ • Facebook: / beingtoppr • Twitter: / mytoppr • Instagram: / mytoppr • LinkedIn: / toppr-com
