Question

what are blood groups???? ​

Answer 1

Answer:

Explanation:

blood type (also called a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs).

Answer 2

Blood Group

Explanation:-

Introduction

• Based on the presence and absence of antibodies, the blood is classified into different groups.
• Further, while classification, the presence and absence of the inherited antigenic substances also considered.
• The types of blood groups are inherited and represent contributions from both the father and the mother.

1. ABO Blood Group System

• In human blood, usually, there are two antigens and antibodies.
• The two antigens are antigen A and antigen B.
• The two antibodies are antibody A and antibody B.
• The antigens are remaining in the red blood cells, whereas the antibodies are found in the serum.
• Based on the antigen property, the blood group of all human beings can be classified as −

➭ Blood Group A − antigen A and antibody B

➭ Blood Group A − antigen A and antibody B➭ Blood Group B − antigen B and antibody A

➭ Blood Group A − antigen A and antibody B➭ Blood Group B − antigen B and antibody A➭ Blood Group AB − antigen A and antigen B and no antibody

➭ Blood Group A − antigen A and antibody B➭ Blood Group B − antigen B and antibody A➭ Blood Group AB − antigen A and antigen B and no antibody➭ Blood Group O − no antigen, but antigen A as well as antibody B

• Consideration of the ABO system is the most imperative while transfusion of human blood.
• The ABO blood group systems were first discovered by Karl Landsteiner in 1901.

2. Rh Blood Group System

• The Rh system (the meaning of Rh is Rhesus) is another significant blood-group system. It is very important to match Rh system while blood transfusion.
• Rh antigen first studied in Rhesus monkeys; therefore, its name is given Rh factor/system.
• The person who does not have Rh antigen is known as Rh negative (Rh-ve) and the person who has the Rh antigen is known as Rh positive (Rh+ve).
