Question

write the paragraph on the importance of blood group and their types

Answer 1

The blood group is the presence of specific antigens on surface of red blood cells. There are antibodies raised in serum against these antigens. Blood group is very important in blood transfusions as if a person is given blood different from his/hers, antibodies will be raised against his/her red blood cells which would lead to hemolysis of RBCs.
There are four different types of blood groups as mentioned below:

Blood Group	Antigen on RBC	Antibody on plasma	Donor’s Group
A	A	Anti B	A, O
B	B	Anti A	B, O
AB	A, B	Nil	AB, A, B, O
O	Nil	Anti A, B	O

• Universal Donor − Blood group ‘O’
• Universal recipient − Blood group ‘AB’
