The body’s prime defense against disease – causing pathogens or cancer
Immune System The body’s prime defense against disease – causing pathogens or cancer These have molecules on them that trigger a response of the immune system called ANTIGENS
2
Structure and Function of the Immune System
Lesson 1
3
Do Now Brain Pop Video Immune System Multiple Choice worksheet
4
Immune Response The immune system is the body's defense against infectious organisms and other invaders. Through a series of steps the immune system attacks organisms and substances that invade body systems and cause disease.
5
Antigen A substance which stimulates the production of antibodies by the immune system which will attack and destroy the foreign pathogen
6
Antibodies Type of protein Produced in response to a detected antigen
Each antibody is unique and fights of specific antigens
7
Lymphatic System Contains immune cells to protect against foreign invaders Contains nodes which filter infection
8
Transplants Sometimes the immune system attacks transplanted organs “rejection” Immunosuppresent drugs can be taken to decrease the activity of the immune system Leaves the patient vulnerable to infection
9
Allergies Allergic reactions response to normally harmless substances ex: dust, pollen, cats release of histamines sneezing, hives, swelling, breathing difficulties ** can take an anti-histamine to relieve symptoms
10
Immunity Active Passive
Infection (production of antibodies which recognize a specific antigen) Immunization (vaccine) Passive Material transmission of resistance Antibody transfer
11
Make a Vaccine Obtain pathogen (polio, small pox, measles, mumps, rubella, tetanus, chicken pox, HPV) Treat to kill or weaken Inject into organism Body makes antibodies and WBC’s to attack Some WBC remain and remember pathogen attack quickly if seen again

AIDS Acquired Immunodeficiency Syndrome
Disease of the Immune System – caused by a virus = HIV (Human Immunodeficiency virus) -- damages immune system by killing helper T-cells --Inactive for years --When activated if leaves patient unable to fight infections or cancer
18
Transmission of AIDS: 1. Sexual contact (body fluids) 2. Blood to blood (transfusions, IV drugs) 3. Mother to baby Over 2 Million people infected! Prevention of AIDS: 1. Abstinence 2. Condoms 3. No drugs
