How our blood groups are different?
Explain.
Answers
Answer:
There are 4 main blood groups defined by the ABO system:
blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma
blood group B – has B antigens with anti-A antibodies in the plasma
blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma
blood group AB – has both A and B antigens, but no antibodies
Blood group O is the most common blood group. Almost half of the UK population (48%) has blood group O.
Receiving blood from the wrong ABO group can be life threatening. For example, if someone with group B blood is given group A blood, their anti-A antibodies will attack the group A cells.
This is why group A blood must never be given to someone who has group B blood and vice versa.
As group O red blood cells do not have any A or B antigens, it can safely be given to any other group.
The NHS Blood and Transplant (NHSBT) website has more information about the different blood groups.
Answer:
If you’ve ever needed a blood transfusion, or donated blood, you probably would have been asked your blood type. While it was once thought all blood was the same, we now know there are different types of blood, called blood groups. Transfusions between blood groups can be catastrophic, even deadly, so knowing the blood type of donors and recipients is of the utmost importance.
Our bodies contain trillions of red blood cells. Each is covered in an array of proteins and sugars, inherited from our parents, which determine our blood group. We can all be classified into group A, B, AB or O, based on which sugars coat our red blood cells.
We’re also classified as positive or negative, based on whether our blood cells carry a protein called the Rhesus D (RhD) antigen. These two blood group systems (ABO and Rh) give us the eight main blood types: O-, O+, B-, B+, A-, A+, AB-, AB+.
