Lymphatic System Study Guide Chapter 16 ) Revised OVERVIEW The lymphatic system has two major functions: (1) it helps maintain fluid balance in the tissues of the body, and (2) it has a major role in the defense against infection. This chapter describes the general functions of the lymphatic system (objective 1). in the discussion of fluid balance, this chapter describes the major lymphatic pathways, lymph formation, and circulation (objectives 2-4). in discussing the defense function, it explains lymph nodes, their location, and their function (objectives 5 and 6). Specific and nonspecific body defenses, and the functions of the thymus, spleen, lymphocytes, and immunoglobulins (objectives 7-10) are discussed. Various types of immune responses, including primary and secondary responses, active and passive responses, allergic reactions, and tissue rejection reactions (objectives 11-13) are also explained. Study of the lymphatic system completes the knowledge of how fluid is transported to and from tissues. Knowledge of the immune mechanisms of the lymphatic system is the basis for understanding how the body defends itself against specific kinds of threat. CHAPTER OBJECTIVES After you have studied this chapter, you should be able to: 1. Describe the general functions of the lymphatic system. 2. Describe the location of the major lymphatic pathways. 3. Describe how tissue fluid and lymph form and explain the function of lymph. 4. Explain how lymphatic circulation is maintained and describe the consequences of lymphatic obstruction. 5. Describe a lymph node and its major functions. 6. Describe the location of the major chains of lymph nodes. 7. Discuss ihe functions of the thymus and spleen. 8. Distinguish between specific and nonspecific immunity, and provide examples of each. 9. Explain how two major types of lymphocytes are formed and how they function in immune mechanisms. 10. Name the major types of immunoglobulins and discuss their origins and actions. 11. Distinguish between primary and secondary immune responses. 12. Distinguish between active and passive immunity. 13. Explain how allergic reactions, tissue rejection reactions, and autoimmunity are related to immune mechanisms. Focus QUESTION Several days after falling and scraping your knee, you notice that the area around your knee is swollen and that you have several enlarged lymph nodes in your groin. How are these signs related to the function of the lymphatic system in maintaining fluid balance and responding to injury and infection? STUDY ACTIVITIES I.
