A&P II Study Objectives
Lymphatic- Immune System
1. Describe the structure and function of each member organ or tissue of the
lymphatic immune system in the following list:
-spleen
-lymph vessels
-red bone marrow
-lymph node
-lacteals
-tonsil
-thymus
2. Describe three functions of the lymphatic-immune system
3. Describe the lymphatic circulation using the following terms:
Valves
Milking action
Right Lymphatic Duct
Thoracic Duct
Subclavian Veins
________________________________________________________________________
1. Define the general term, non-specific immune response.
2. Discuss the first line of defense in non-specific immunity, i.e. suface –membrane
barriers
3. Briefly summarize the aspects of the second line of defense in non-specific
immunity: phagocytosis, inflammation, and immune chemicals such as
complement,etc..
4. Describe the series of events in the inflammatory response. Be sure to include the
“cause” of each of the three inflammation symptoms: redness, swelling, and pain.
5. Discuss the “trigger “ for the inflammatory response.
6. Explain the following statement: “Inflammation can occur without infection, but
infection is always accompanied by inflammation.”
7. Describe the process of phagocytosis by monocytes and neutrophils.
8. Explain how fever protects the body against invading pathogens.
9. Describe the third lymphocyte, natural killer cells, and explain their role in
immunity.
10. Compare and contrast the terms antigen and antibody.
11. Briefly describe antibody structure.
12. Briefly describe the clonal-selection theory of B-cell production.
13. Describe the “B-cell response” or humoral, circulating immunity. Include the
following: activation of B-cell, clonal expansion, Antibody production, B-plasma
and memory cells, and secondary amnestic response.
14. Explain antibody method of action.
15. Describe the “T-cell response”or cell-mediated immunity. Include the following:
activation by macrophage presentation, clonal expansion, resulting T-cell types
and their roles.
16. List the immunochemicals produced primarily by T-helper cells and briefly
describe their “command and control” chemical communication function in the
immune response.
17. Distinguish between active and passive immunity.
18. Explain why the AIDS virus “wins” against specific immunity due to its
destruction of T-helper cells.
19. Briefly describe hypersensitivity reactions (allergies)
20. List and describe some auto-immune disorders and diseases.
