LYMPHATIC SYSTEM REVIEW SHEET 2
1. Lymphatic tissue consists of reticular fibers, fibroblasts, and macrophages
2. Lymphatic nodules differ from lymphatic organs in that the nodules filter the lymph
3. Function of the lymphatic system, returns proteins to the blood, transports absorbed fats to the blood, protects
against foreign invasion
4. Blood and lymph are similar because both possess white blood cells
5. The anatomical feature of lymph capillaries that distinguishes them from blood capillaries is that lymph
capillaries possess overlapping ends
6. Lymphatic and veins are similar because they possession of value, carry fluid towards the heart, possession of
thinner walls than arteries
7. Lymph is a clear liquid except for digestive viscera (white) due to high fat content
8. Function of lymph nodes to, produce lymphocytes, sites of phagocytic activity, sites of antibody production
9. Suppose bacteria and lymphocytes are found in the lymph prior to entering a lymph node. What would the lymph
most likely contain after it leaves the node? less bacteria, more lymphocytes
10. Function of the spleen, stores red blood cells, produces lymphocytes, phagocytizes RBC’s an bacteria
11. The two main collecting channels of the lymphatic system are the right lymphatic duct and thorasic duct
12. Aid lymph flow through the body? Values, skeletal muscle contraction, breathing
13. Most SPECIFIC form of resistance? antibody response
14. Mechanical process (Innate Defense) used to expel microorganisms from the body? cilia activity, intact skin,
mucous
15. Interferon, prevents viral replication by blocking protein synthesis
16. Involved with the activity of antibodies, complement, B cells, immunoglobin
17. Complement enhances the body’s ability to destroy microbes
18. B cells are antigen-binding and the initial defense in Adaptive Immunity?
19. Phagocytes are similar to macrophages?
20. Phagocytosis can be thought of as occurring in four stages. chemotaxis, adherence, ingestion, digestion
21. Consequence of vasodialation and increased permeability in the process of inflammation is increased blood flow
to the injured site
22. Histamine along with kinins and prostaglandins contribute directly to vasodialation
23. Recovering from a disease such as polio would leave antibodies in the individual’s serum. This type of immunity
is called naturally acquired active immunity
24. Found in a vaccine, live microbes, dead microbes, antibodies
LYMPHATIC SYSTEM REVIEW SHEET 2
25. Examples:
a. recovering from the chickenpox naturally acquired passive immunity
b. receiving the polio vaccine artificially acquired active immunity
c. receiving an injection of gamma globulin artificially acquired passive immunity
d. receiving antibodies through the placenta artificially acquired active immunity
26. The immunogenicity of an antigen is the ability to stimulate antibody production
27. Antigens are generally recognized as “self”
28. An antigen so small that it possesses only one antigenic determinant site is called a(n) hapten
29. Another name for immunoglobin is antibody
30. Naturally Acquired Active Humoral Immunity is mediated by sensitized B lymphocytes
31. T cell important in preventing an autoimmune disease such as rheumatoid arthritis is suppressor cells
32. The secondary response in an immune response to a specific antigen is an allergic reaction to the specific antigen
33. A person is exposed to a bacterial antigen as a child. A few years later this person somes in contact with the same
microbe but shows no signs or symptoms of the disease. What is the most likely explanation, the secondary
response was fast, destroying the microbe due to presence of memory cells
34. Langerhans and Granstein cells are involved in the immune response and are found in the skin
35. Death from AIDS is usually due to an opportunistic secondary infection
36. A vaccine contains dead or attenuated pathogens
37. When a baby is born it has some antibody protecting that it received from its mother as antibodies crossed over
the placenta. This is an example of Naturally Acquired Passive Immunity
38. A lymph organ important in early childhood for developing memory cells that will atrophy with age is the thymus
39. A lymph organ that is located adjacent to the intestinal walls to destroy large numbers of ingested bacteria and to
produce memory cells is Peyer’s Patches

40 Cell of the immune system to its function.
Complement 20 plasma proteins that enhance the body’s ability to destroy microbes in a cascading effect.
B cell is antigen binding cells.
Cytokines are T cell stimulators released by activated T cells.
Memory cells are descendants of activated B cells that remembers antibodies needed for an antigen.
NK cells use perforins a cytolytic chemical that disintegrates the target cell’s nucleus.
Killer T cell is the most lethal cell for destroying microbes, the final defense.
Interleukins are T cell stimulators released by activated macrophages.
Helper T cells release cytokines to stimulate production of B and T cells.
Macrophage utilize phagocytosis to consume microbes. (chemotaxis, adherence, ingestion, digestion)
Interferon is secreted by cell that is lysised by a virus that diffuses to nearby cells to stimulate synthesis of PKR
that interferes (blocks) protein synthesis.
51. Suppressor T Cells slow the activity of B and T cells.
