Write About Blood Groups And Their Importance
Answers
Answer:
The importance of knowing your blood type is to prevent the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery. If two different blood types are mixed, it can lead to a clumping of blood cells that can be potentially fatal.
Explanation:
The ABO classification is the most important and relevant for blood compatibility. ... There are over 30 known blood group systems, though the two main ones are the ABO and the Rh group. Blood group O has no antigens, but both anti-A and anti-B antibodies in the plasma, as well as some special “anti-A,B” antibodies.
Answer:
The human body contains around 8 to 10 pints of blood depending on the size of the individual. However, the composition of the blood is not the same in each person. This is what makes the person’s blood type.
Group A: The surface of the red blood cells contains A antigen, and the plasma has anti-B antibody that would attack any foreign B antigen containing red blood cells.
Group B: The surface of the red blood cells contains B antigen, and the plasma has anti-A antibody that would attack any foreign A antigen containing red blood cells.
Group AB: The red blood cells have both A and B antigens, but the plasma does not contain anti-A/anti-B antibodies. Individuals with type AB can receive any ABO blood type.
Group O: The plasma contains both types of anti-A/anti-B antibodies, but the surface of the red blood cells does not contain any A/B antigens. Having none of these A/B antigens means that they can be donated to a person with any ABO blood type.
It is important to confirm a person’s blood type when they are donating blood or receiving a transfusion.
If someone with group B antigen receives red blood cells from someone with group A antigen, their body will reject the transfusion.
This is because patients with B antigen on their red blood cells have anti-A antibody in their plasma. The anti-A antibody in the plasma then attacks and destroys the A antigen donor red blood cells. This can be fatal.
Some red blood cells have the Rh factor, which is also called RhD antigen.
Rhesus grouping adds another dimension.
If the red blood cells contain the RhD antigen, they are RhD positive. If they do not, they are RhD negative.
