Key terms used in exam questions Pathogen An microorganism that causes an infectious disease Antibiotic A chemical that kills bacteria Antiseptic A chemical that is used externally to prevent the spread of pathogens. 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. 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. .

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.
