Lymphocytes play a primary role in the body's immune response. They are a type of white blood cell responsible for recognizing and attacking foreign substances such as viruses, bacteria, and cancer cells. Erythrocytes are red blood cells that carry oxygen and carbon dioxide, while antigens are substances that provoke an immune response. Antibodies are proteins produced by the immune system in response to antigens and play a role in fighting infection.
