3. IMMUNE SYSTEM My organ system is the Immune System. The job of the immune system is to fight off diseases. Also it helps get rid of infections and inflammation in the skin It also controls internal activities in order to prevent damage it other parts of the body. The Immune system has some adaptive traits that allow it to isolate certain pathogens and help your body become immune to them The Immune System is an amazing system and has the ability to cells that are uniquely yours. Any other cells that come into the body that aren't yours are attacked and immediately terminated.

5. IMMUNE SYSTEM PARTS Antibodies- cells of the immune system that recognize foreign organisms that invade the body Epidermis- Dead cells that cover the body aka skin and provide a 2 nd layer of dividing cells Cilia- Tiny hair like fibers that protrude from a cell. Commonly found in the respiratory system these tiny hairs constantly move in order to break up and move mucus and debris Thymus- An organ in the lower part of the neck that produces cells to fight infection White Blood Cells- The white blood cell count rises in cases of infection and other conditions in order to fend off the unwanted bacteria. A low white blood cell count can increase the risk of infection or disease related illnesses Mucus- A thick gel substance that moistens and protects organs Saliva- A watery mixture of chemicals that moistens the oral wall

6. LINE OF DEFENSE IMMUNE SYSTEM The first line of defense is the skin, Mucous membranes, hairs and cilia, gastric juice and urine, tears, sweat and saliva, and Cerumen The skin provides an impenetrable barrier against pathogens The mucous membrane traps foreign particles and directs them out of the body Hairs and cilia trap dust and dirt Gastric juice and urine are acidic substances that have a protective function Tears, sweat and saliva are body fluids with antibiotic properties Cerumen is produced in the ear canal and traps dust and dirt

7. LINE OF DEFENSE IMMUNE SYSTEM The second line of defense are Leucocytes are white blood cells that attack the pathogen that invades the body before it can harm the body. The third line of defense is the specific immune response. The specific immune response recognizes your unique cells and sends out antibodies against and cells that are not your own.

8. VACCINATIONS Vaccinations expose people safely to germs so that there immune system can get better equipped to fight off the infection. During the flu outbreaks, shingles occur, or pneumococcal disease is seen doctors give patients vaccinations so that there body can adapt to it without getting the disease itself

9. TEAMWORK The Immune System is great with teamwork The cilia that lines the respiratory system help keep dirt and mucus out of the air ways The digestive juices help dissolve and destroy any foreign bacteria in the digestive system And finally the Immune System works mainly with the circulatory system because the circulatory system transports the immune cells to other parts of the body

10. FUN FACTS Stress hormones weaken the immune system Antibacterial products can hinder the immune system Positive events have helpful impact on immune system Allergies, for example, are a mistake by the body’s immune system
