What is the primary function of antibodies in the immune system?

The primary function of antibodies in the immune system is to bind to and neutralize specific antigens. Antibodies, also known as immunoglobulins, are proteins produced by B cells in response to foreign substances, such as pathogens or toxins. Each antibody has a unique structure that allows it to specifically recognize and attach to a particular antigen, which is any substance that can provoke an immune response.

By binding to antigens, antibodies can neutralize them directly, preventing them from interacting with and damaging host cells. Additionally, the binding of antibodies to antigens can mark these antigens for destruction by other components of the immune system, facilitating their removal. This dual role of attenuation of pathogen effects and tagging for destruction is crucial for the effective functioning of the immune response.

In summary, the capacity of antibodies to specifically recognize and bind to antigens underlies their fundamental role in neutralizing threats and orchestrating a coordinated immune response.
