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. .

By Renira Rugnath and Jeshanah Johnson . Basics . Homeostasis, or a "steady state," is a continual balancing act of the body systems to provide an internal environment that is comparable with life. The two liquid tissues of the body, the blood and lymph have separate but interrelated functions in maintaining this balance. They combine with a third system, the immune, to protect the body against pathogens that could threaten the organism's viability. . 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 . iPS. cells, self-renewal, differentiation, pluripotent, multipotent, Inner cell mass, Nuclear transfer (Therapeutic cloning), Feeder cells, LIF, embryoid body..

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. Immunology. Study of the components and function of the immune system. Immune System . Molecules, cells, tissues and organs which provide non-specific and specific protection against. Microorganisms. 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..
