Individuals with type A blood produce anti-B antibodies and individuals with type B produce anti A. There are many sub groups of blood antibodies such as D (Rh) but we usually only refer to the ABO systems.
B-cells
Type A blood will produce antibodies against B antigens.
A type of white blood cell called a lymphocyte, or more specifically a B lymphocyte produces antibodies.
anti-B
No, type A blood does not have B antibodies.
Since that person has anti-B antibodies, then A antigens are present in her red blood cells. Since that person doesnt have anti-A antibodies, then there are no B antigens present, which means the person has A type blood.
B lymphocytes.
For ABO antibodies, group A has anti-B.
A - blood type
B Cells
B Cells mature in bone marrow and produce antibodies
Individuals with blood type A positive have antibodies against blood type B antigens. This means their immune system reacts against blood from individuals with blood type B if they were to receive a transfusion containing type B blood.
