Question

write a short note on blood group​

Answer 1

Hi..... Here is ur answer

There are four main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents.

Each group can be either RhD positive or RhD negative, which means in total there are eight main blood groups.

Blood is made up of red blood cells, white blood cells and platelets in a liquid called plasma. Your blood group is identified by antibodies and antigens in the blood.

Antibodies are proteins found in plasma. They're part of your body's natural defences. They recognise foreign substances, such as germs, and alert your immune system, which destroys them.

Antigens are protein molecules found on the surface of red blood cells.

Hope this is helpful in soem extend :)

Answer 2

Hii mate, ✌✌

your answer is ⬇️

=》BLOOD GROUP:- A scientist named Karl Landstiener ( 1868 - 1943 ) , for the first time gave the concept of the Blood Groups. It came to know that the blood group of the donor and the recepient should be the same. Donor is one who gives the blood and the recepient is one who gets the blood. If unknowingly blood of a different blood group is transfused to a patient, then blood gets clotted and blood flow gets hindered. In this case the recepient may even die.

After the knowledge of blood groups , it was found that, blood has two types of protein-

( 1 ) Antigen

( 2 )Antibody

( 1 ) Antigen = Two types of antigen are found in humans blood: antigen A and antigen B

( these are represented as 'A' and 'B' )

( 2 ) Antibody = Like Antigens, Antibodies are also two types- antibody 'a' and antibody 'b'( these are represented as 'a' and 'b' )
