Antibody: Key to Immune Protection

What is the key function of an antibody in the immune system?

Choose the SYNONYM for the vocabulary word antibody. a alloy b diversity c concise d immune protein

Answer:

The correct answer is D. Antibodies are immune proteins that play a crucial role in protecting the body against harmful pathogens.

Antibodies, also known as immunoglobulins, are Y-shaped proteins produced by the immune system to identify and neutralize foreign invaders such as bacteria and viruses. These immune proteins are a vital component of the immune response and provide a targeted defense against specific antigens.

When a pathogen enters the body, the immune system generates antibodies that bind to the antigen markers on the surface of the invader. This binding marks the pathogen for destruction by other immune cells, such as macrophages and T cells, leading to the elimination of the threat.

Antibodies also play a crucial role in the immune memory response. Once the immune system has successfully fought off a specific pathogen, it retains a memory of the invader by storing the antibody blueprint. This memory allows the immune system to mount a faster and stronger defense if the same pathogen reappears in the future.

There are five main types of antibodies: IgA, IgD, IgE, IgG, and IgM, each with specific functions in the immune response. These antibodies work together to provide a comprehensive defense against a wide range of pathogens and help maintain overall health and well-being.
