Immune Response
When an infection develops, the Overview of the Immune System also responds by producing several substances and agents that are designed to attack the specific invading microorganisms ( see T cells (a type of white blood cell) that can recognize and kill the invading microorganism Antibodies that target the specific invading microorganism Antibodies attach to and immobilize microorganisms. They kill them outright or help neutrophils target and kill them. How well the immune system defends the body against each microorganism depends partly on a person's genetic make-up.
