PPT-Concepts of Biology: The Immune System and Disease

This smallpox variola vaccine is derived from calves exposed to cowpox virus Vaccines provoke a reaction in the immune system that prepares it for a subsequent infection by smallpox Viewed .

Immunity is the state of protection against foreign pathogens or substances (antigens). Latin term . 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.. 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.. others who are interested in the e30ects of smoking on overall health The single largest cause of preventable disease and death is smoking people who want healthy lives should not smoke Nearly half a In this compound light micrograph purple-stained neutrophil (upper left) and . eosinophil (. lower right) are white blood cells that float among red blood cells in this blood smear. .

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. Chapter 7: The Cellular Basis of Inheritance.
