Immune & System MDCAT Quiz: The immune system is the body’s defense mechanism against harmful pathogens such as bacteria, viruses, fungi, and parasites. It comprises cells, tissues, and organs that work in concert to identify and neutralize foreign invaders. In the case of MDCAT students, knowledge of how the immune system works is important for answering questions on immunity, immune responses, and functions of various immune cells. The MDCAT Quiz will test your knowledge of the components of the immune system and how it protects the body from infections.
Components of the Immune System
This paper describes the components that makeup the immune system. They include white blood cells, antibodies, the lymphatic system, and special organs such as the spleen and thymus. White blood cells, for example, T-cells and B-cells, recognize and destroy microorganisms. In addition, the MDCAT Quiz seeks to test various types of immune cells and their functions, antigen presentation, and how the immune response is initiated. From these points, one can now appreciate how an immune response to pathogens occurs in the body.
Innate and Adaptive Immunity
The immune system operates through two main types of immunity: innate and adaptive. Innate immunity refers to the first line of defense by the body, such as physical barriers of skin and mucous membranes, and cellular responses like phagocytosis. Adaptive immunity, on the other hand, is a much more specific response that involves the activation of lymphocytes and the production of antibodies that are highly adapted to each pathogen. The flashcard will provide information that you need to know concerning innate and adaptive immunity in terms of how these types of immunity work and their role in protection against body infections.
