Chapter 14 Review: Lymphatic System and Immunity
Know the following:
 Identify the major components of the lymphatic system and explain their functions.
 Discuss the importance of lymphocytes and describe where they are found in the body.
 List the body’s nonspecific defenses and explain how each functions.
 Define specific resistance and identify the forms and properties of immunity.
 Distinguish between cell-mediated immunity and antibody-mediated (humoral)
immunity.
 Discuss the different types of T cells and the role played by each in the immune
response.
 Describe the structure of antibody molecules and explain how they function.
 Describe the primary and secondary immune responses to antigen exposure.
 Relate allergic reactions and autoimmune disorders to immune mechanisms.
