Innate immune svstem 1. Explain and describe the various lines of defense against pathogens. 2. Outline the major components of the innate immune system including what initiates and the benefits of each defense . 3. Outline the sequence of events that occurs in phagocytosis. 4. Describe the general complement reactions and list their 5 benefits. 5. List the origins and actions of several cytokines including interleukins, histamines, leukotrienes, prostaglandins, tumor necrosis factor and colony stimulating factor. 6. Outline and describe the events occurring in the inflammation response to an invading bacterium. 7. Differentiate between the populations of WBCs (granulocytes and agranulocytes) in terms of morphology and physiological effect. 8. Describe the anatomy and physiology of the primaryand secondary lymphatic organs including: bone marrow, thymus, lymph nodes, spleen, peyers patch and tonsils 9.
