Innate immunity. . is considering first line of defense, an immediate response to a pathogen that does not confer lifelong protective immunity. It is includes :. Dr. . M.A.Thomas. . FUNCTIONS . OF THE IMMUNE SYSTEM. :. Recognize. , destroy and clear a diversity of pathogens. .. Initiate . tissue and wound healing processes. .. Recognize . and clear damaged self components. The resistance that an individual acquires during life by recognising and selectively eliminating specific foreign molecules is known as acquired immunity.. This is displays four characteristic features:. Features of adaptive immunity:. Adaptive immunity is characterized by the following:. 1. Antigenic specificity: (. highly specific).. 2. Diversity : . ( each antigen there is specific T-cell and B-cell for it).. OA. OBJECTIVES. At the end of the lecture, students will be able to:. Explain the role of the immune system. Describe the two types of immunity. Explain antibodies and its various types. Define immunodeficiency.
