Explanation:

Detailed explanation-1: -How Does the Immune System Work? When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.

Detailed explanation-2: -In an immune response, the immune system recognizes the antigens (usually proteins) on the surface of substances or microorganisms, such as bacteria or viruses, and attacks and destroys, or tries to destroy, them.

Detailed explanation-3: -In summary, non-self antigens are foreign substances that trigger an immune response, self-antigens are substances that are normally present in the body and are not attacked by the immune system and allergens are a type of non-self antigen that causes an abnormal immune response known as an allergic reaction.
