MICROANATOMY

Detailed explanation-1: -Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen.

Detailed explanation-2: -An immune complex is an antibody attached to an antigen. An immune response is the reaction of the immune system to an antigen. Immunoglobulin is another name for antibody. Interleukin is a type of messenger (cytokine) secreted by some white blood cells to affect other white blood cells.

Detailed explanation-3: -If an antigen enters the body and B-cells recognize it (either from having had the disease before or from being vaccinated against it), B-cells will produce antibodies. When antibodies attach to an antigen (think a lock–key configuration), it signals other parts of the immune system to attack and destroy the invaders.
