*NEW* Review Questions
Learning Objectives
At the end of this unit, you should be able to:
I. Describe the major functions and anatomical organization of the lymphatic system.
II. Distinguish between the cardiovascular system and the lymphatic system.
III. Explain nonspecific (innate) resistance to disease and specify the general components of nonspecific (innate) resistance.
IV. Explain specific (adaptive) resistance to disease (immunity), and distinguish between T-cell mediated (cellular) immunity and B-cell mediated (humoral) immunity.
V. Specify the ways in which antibodies destroy or inactivate a foreign substance in the body.
VI. Discuss the relationship between antibodies and immunization and specify four ways of conferring immunity.
VII. Describe conditions that may result due to a compromised immune system.
VIII. Describe the basis of the ABO blood groups and Rh factor and explain the significance of this to transfusions and hemolytic disease of the newborn.
Learning Objectives and Guiding Questions
At the end of this unit, you should be able to complete all the following tasks, including answering the guiding questions associated with each task.
I. Describe the major functions and anatomical organization of the lymphatic system.
- For each of the following components of the lymphatic system, state its major function(s) and describe its location(s) in the human body:
- Lymphatic vessels
- Lymph
- Primary lymphoid organs
- Secondary lymphoid organs
- Describe the anatomical relationship (i.e. where they are located relative to each other) between lymphatic vessels, lymph, and lymph nodes.
II. Distinguish between the cardiovascular system and the lymphatic system.
- Compare and contrast the lymphatic and cardiovascular systems by describing:
-
- Any function(s) that both systems serve.
- Differences between the functions of the two systems.
- Similarities in the overall structure (cell types, tissue types, organs) of the two systems.
- Differences between the overall structures found in the two systems.
III. Explain nonspecific (innate) resistance to disease and specify the general components of nonspecific (innate) resistance.
- What are the main mechanisms that provide the human body with nonspecific resistance to infection?
- Describe the physical and chemical mechanisms used by each of the following tissues to provide the body with a barrier to disease:
- The skin
- Mucous membranes
- Compare and contrast the physical mechanisms used by the skin to provide the body with a barrier to disease with those used by mucous membranes.
- Compare and contrast the chemical mechanisms used by the skin to provide the body with a barrier to disease with those used by mu
