Question

Which blood type carries anti-a antibodies in the plasma?

Answer 1

Individuals with type B blood carry anti-A antibodies in their plasma. This immune response targets any foreign A antigens that might enter the body, such as through a blood transfusion.

Step-by-step explanation:

People with type B blood carry anti-A antibodies in the plasma. This is because they have the B antigen on the surface of their red blood cells (RBCs) and, therefore, their immune system produces anti-A antibodies to target anything that is not recognized as self. These antibodies will attack foreign A antigens if they enter the body, such as through a blood transfusion. On the other hand, individuals with type A blood produce anti-B antibodies, while those with AB blood do not produce either anti-A or anti-B antibodies. People with type O blood, which lacks both A and B antigens on their RBCs, produce both anti-A and anti-B antibodies.

Answer 2

The blood type B carries anti-A antibodies in the plasma. Blood type B is characterized by the presence of B antigens in the plasma membrane of the red blood cells. With the B antigens present, the opposite (anti-A) antibodies should be present in the plasma. Same goes with other blood types. In blood type A, there is the presence of A antigens on the RBC membrane and anti-B antibodies in the plasma. In blood type O, there are no antigens on the RBC membrane therefore there is the presence of both anti-A and anti-B antibodies in the plasma. In blood type AB, there are both the A and B antigens on the RBC membrane but no antibodies in the plasma.
