<u>Type B blood has B antigens with anti-A antibodies in the plasma</u>
Blood is formed up of red blood cells, white blood cells and platelets in a liquid called plasma. Your blood group is recognized by antibodies and antigens in the blood. Antibodies are proteins detected in plasma. They recognize foreign substances, such as germs, and inform your immune system, which murders them. Antigens are protein molecules located on the cover of red blood cells.
