Antibodies in the Immune System Quiz

Function of Antibodies

• Primary function is to identify and neutralize foreign objects like bacteria and viruses.
• They tag pathogens for destruction by other immune cells, facilitating targeted immune response.

Composition of Antibodies

• Antibodies are composed of proteins, specifically made up of four polypeptide chains: two heavy chains and two light chains.
• Each antibody has a unique variable region that allows it to bind specifically to antigens.

Role of Antibodies in the Immune System

• Antibodies play a critical role in mediating immune responses by marking pathogens for destruction.
• They can neutralize toxins and block interactions between pathogens and host cells, preventing infection.

Production of Antibodies in the Body

• Antibodies are produced by B lymphocytes, a type of white blood cell.
• Upon activation by an antigen, B cells differentiate into plasma cells, which secrete antibodies into the bloodstream.

Triggers for Antibody Production

• Antibody production is triggered by exposure to antigens, which can be components of pathogens or foreign substances.
• Vaccination can also stimulate the immune system to produce antibodies against specific pathogens without causing disease.
