How does the body's immune response operate to fight infection?

Short version: The body starts to produce antibodies.

The body's immune system contains lots of white blood cells.

Lymphocytes and phagocytes are a type of white blood cell. The lymphocyte detects the pathogen that could lead to an infection, and produces the antibody needed to kill the pathogen. The antibody attaches to the pathogen and then the phagocyte comes along and engulfs it, destroying and eating it.
