Question

How do antibodies and antigens work together in the blood?

Answer 1

Antigens are the substance that stimulates an immune response, specifically activating lymphocytes, which are the body’s infection-fighting white blood cell.

Complete answer:
Antibody is a protective protein produced by our immune system also known as immunoglobulin in response to the presence of a foreign substance that is an antigen. Antibodies first recognize and then latch onto antigens so that Antigens can be removed by antibodies from the body.

Antibodies activate the complement system to kill bacterial cells by lysis (punching holes in the cell wall)
Immune cells destroy the antigen by attaching to a particular antigen. Attaching makes it easier to remove antigens . T lymphocytes attack directly to antigens and help control the immune response. They too release chemicals which are known as cytokines, which control the entire immune response.

B lymphocytes (or B cells) are each programmed to make one specific antibody for a B cell which comes across its triggering antigen; it gives rise to many large cells known as plasma cells. Each plasma cell is responsible for the production of antibodies.

Antigens are atoms fit for activating a resistant reaction. Every antigen has unmistakable surface highlights, or epitopes, bringing about explicit reactions.

Note: IgG, IgM, IgA, IgD, IgE are the five types of antibodies in humans to try that are classified according to the type of heavy chain constant region, and these antibodies are distributed and function differently in the body.
