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. Reaves. KEY CONCEPT:. The immune systems consists of organs, cells, and molecules that fight infections.

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?. Key attributes of immune system. 4 attributes that characterize the immune system as a whole. specificity. antigen-antibody specificity. diversity. react to millions of antigens. memory. rapid 2° response. The Immune Syste m Before the 1900’s, no one knew what caused sickness and infection Most people thought evil spirits, swamp gas, or bad luck caused disease science history Louis Pasteur Theorized that microbes caused disease and killing them could prevent illness.

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 immune systems consists of organs, cells, and molecules that fight infections. Many other tissues and systems help the immune system. Skin. is a physical barrier to infection. Mucous membranes. trap pathogens entering the body. 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 . To protect the body from infection or disease. Can be infectious or noninfectious. Infectious Disease.

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..
