Detailed explanation-1: -What are antibodies? Antibodies are proteins that protect you when an unwanted substance enters your body. Produced by your immune system, antibodies bind to these unwanted substances in order to eliminate them from your system. Another word for antibody is immunoglobulin.
Detailed explanation-2: -Antigens are classically defined as any foreign substance that elicits an immune response. They are also called immunogens. The specific region on an antigen that an antibody recognizes and binds to is called the epitope, or antigenic determinant.
Detailed explanation-3: -Lymphocytes are a type of white blood cell. There are B and T type lymphocytes. B lymphocytes become cells that produce antibodies. Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen.
