Disease causing organism, “sickness maker” Pg 55 Disease causing organism, “sickness maker” ability of a body to fight infection through the production of antibodies or cells that inactivate foreign substances or cells Markers on a membrane that triggers an immune response Made by the body in response to an antigen Genetic mutation in a cell that causes uncontrolled cell division Preparation that provided active acquired immunity to a particular disease

Physical and Chemical barriers- Skin, mucous membranes, stomach acid Pg 55 Bacteria Fungi Viruses Parasites The immune response has been stimulated and the body is fighting off some type of infection Physical and Chemical barriers- Skin, mucous membranes, stomach acid Inflammatory Response Specific- security guard, Recognize, attack, destroy and remember
