PPT-Chapter 43: The Immune System

Essential Knowledge 2d2 Homeostatic mechanisms reflect both common ancestry and divergence due to adaptation to different environments 433 2d3 Biological systems are affected by disruptions to their dynamic homeostasis 432434. Chapter 40. Agents of Disease. The human body provides a suitable environment for many microorganisms: it is moist, warm and full of nutrients.. Not all microorganisms are harmful; some are beneficial. THE IMMUNE SYSTEM. NONSPECIFIC DEFENSES AGAINST INFECTION INCLUDE THE. SKIN. MUCOUS MEMBRANES. PHAGOCYTIC CELLS. ANTIMICROBIAL PROTEINS. THE IMMUNE SYSTEM. NONSPECIFIC DEFENSE MEANS THAT THEY DON’T DISTINGUISH BETWEEN MICROBES. Additional key terms. Lymph. Having to do with lymph or lymphatic system. Intercellular fluid as it returns to the venous circulatory system. Removes waste products from the cells. Must be filtered by the lymph nodes before it reenters the circulatory system . Solutions to improve treatment. Current . immunosuppressors. …. …suppress the entire immune system, leaving patients more vulnerable to everyday infections and higher rates of cancer.. However, this is necessary because the immune system attacks parts of the body which are work well and are needed (in MS, myelin is targeted, causing demyelination) but we cannot isolate the suppression to just one impact of the immune system so to protect the targeted area we must lower the guard of everywhere else. . The Lymphatic System. Works closely with the immune system to protect and maintain the health of the body. Functions. (3 primary). Absorbing fats and fat soluble vitamins from the small intestine. Removes waste from the tissues. Innate Immunity. Receptors on T and B Cells Are Specific for Each Antigen. Innate and Adaptive Immune Systems. Antigen Presentation. Adaptive Immunity. Function of the Immune System. Tumor Escape Mechanisms. Main Function. The Immune System is used to prevent infection and . disease.. Using . a variety of cells and organs, the Immune System disposes of foreign or harmful antibodies through a process known as the immune response.. 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.. Main Topics for today. Complement System. Cytokines, Chemokines, Growth Factors. Expanding on the Immune Response. Review innate and natural immune response. Antigen capture, presentation. Primary and Secondary immune response. Immunity. Immunity. The ability of the body to fight infection and/or foreign invaders by producing . antibodies or killing infected cells.. Immune System. The system in the body responsible for maintaining homeostasis by recognizing . ecognize. A. ttack. D. estroy . A. nd . R. emember. Bodies defense against pathogens. Immune System recognizes the identity of foreign substances. Antigens are found on the cells of all organisms and your body is able to identify your own cells and tell when a foreign cell has entered the system. What is the Immune System?. The immune system is a vast network of cells and tissues.. Located throughout your body.. Involves numerous types of cells, organs, proteins, and tissues.. The immune system can distinguish between your tissues and foreign tissue/ invaders.. Biology Trending, 4e. Eli Minkoff and Jennifer Hood-DeGrenier. The mind and the body interact. The immune system maintains health. Cells of the immune system and the lymphatic circulation. Innate immunity.
