Immune. System. Factors of Immune Health. A number of factors contribute to immune health. Exercise. Feelings of stress. Nutrition. Essential oils*. *These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.. Chapter 31 Sections 1-4, 6. Pathogens and Human Illness. What are some causes of diseases?. We can have infectious and noninfectious diseases.. Infectious can be passed from one person to another because of germs. What are some examples?. LYMPHOCYTES. Are the key cells of the immune system. Two types: B and T. Both produced in the bone marrow. B matures in the bone marrow. T matures in the thymus. Immunocompetency. B and T lymphocytes must recognize “self.”. AIDS- Acquired . I. mmune . D. eficiency Syndrome, is a serious viral disease that destroys the body’s immune . system. HIV-The virus (Human Immunodeficiency Virus) that causes AIDS.. Of the 40,000 new HIV infections each year, half of those occur in people younger than 25 years old. The specialists who diagnose and treat immune system disorders are called . immunologists. , and the specialty itself is called . immunology. .. Phagocytes. Phagocytes are often the first immune system cells . HIV. (Human immunodeficiency virus)- a virus that attacks the immune system.. Infection with HIV can be prevented. Responsible decisions is the most valuable tool for protection against HIV.. Example: Abstinence from sexual activity and injecting drugs reduce your risk.. Purpose of the Immune System . Protect from internal attacks from . abnormal body cells . (cancerous cells). Protect from . external pathogens. Can enter the body through any systems that have openings on the exterior of the body. Acquired Immune Deficiency Syndrome. The most common secondary immunogenicity disease in the world . Identified in 1981. Serious worldwide epidemic. Prevalence of HIV Infection by Country .
