Q

Immunity

A

Bodys ability to resist foreign organisms anf toxins that damage tissues and organs. This includes natural immunity and adaptive immunity. The Word immunity comes from latin immunis, meaning exempt or pretected from.

Q

Lymph Capillaries

A

Tiniest Lymphatic Vessels

24
Q

Lymph Node

A

Collection of stationary soild lymphatic Tissue along Lymph vessels; Contain cells (Lymphocytes and Macrophages) that Fight infection.

25
Lymph Organs
Lymph Nodes, Spleen, and tymus gland. Tonsils and adenoids are other examples of lymphoid organs
26
Lymph Vessels
Carrier of Lymph thoughtout the body; lymphatic vessels empty lymph into veins in the upper part of chest
27
Macrophage
Large phagocyte found in lymph nodes and other tissue of the body. Phag/o means to wat or swallow
27
Mediastinal Nodes
Lymph nodes in the area between the lungs in the chest cavity
28
Paraaortic Nodes
Lymph nodes near the aorta in the lumbar(waist) area of the body
28
Monoclonal Antibody
anibodie produced in a lab to attack antigens and to destroy cells; useful immunotherapy
28
Natural Immunity
protection that an individual is born with to fight infection such as neutrophil, monocytes, Macrophages, and NK cells. its not antigen specific
28
Plasma cell
Lymphocyte that secretes anitbodies. it natures from B lymphocytes
29
Mesenteric Nodes
Lymph nodes in the mesentery (intestinal region)
30
Right lymphatic Duct
lymphatic vessel in the cheat that drains lymph fronm the upper right part of the body. it empties lymph into a large vein in the neck
31
Spleen
Organ in the upper left quadrant of the abdomen that destroys worn-out red blood cells, activates lymphocytes and stores blood
32
Suppressor T cell (treg)
Lymphocyte that inhibits the activity of B and T cells ( Regulatory T cell)
33
T cell (T lymphocyte)
Lymphocyte that acts directly on antigens to destroy them or produce chemicals (cytokine) such as interferons and interleukins that are toxic
34
Thoratic Duct
Large lymphatic vessels that drains lymph from the lower and left side of the body(head neck arm chest) it empties lymph into large veins in teh neck
35
Thymus Gland
Lymphoid organ in the mediastainum that conditions T cells to reast to foreign cells and aids in the immune response
36
Tolerance
Ability of T lymphocytes to recognize and accept the bodys own antigens as "self; or friendly" once tolerance is established , the immune system will not react agaisnt it
37
Tonsils
Masses of lymphatic tissue in the back of the oropharynx
38
Toxins
Poison; a protein produced by certain Bacteria, animals or plants
39
Vaccination
Exposure of an individual to a foreign protein(antigen) that provokes an immune response
40
Vaccine
Weakened or dead antigen is given to induce production of antibodies. this results in adaptive immunity
41
Anaphylaxis
Exaggerated or unsusalt hypersensitivity to foreign proteins or other substances
41
Allergen
Substance capable Of causing a specific hypersensitivity reaction; a Type of antigen
42
Atopy
Hypersensitive or allergic state involving an inherited predisposition. from the greek work Atopia means strangeness
43
CD4 + cells
helper T cells carry the CD4 protein antigen on their surface. HIV binds to CD4 and Infects and Kills T cells Bearing this protein. AIDS patients have an inadequte number of CD4+ cells
44
Hodgkin Lymphoma
Malignant tumor of Lymphoid tissue in spleen and lymph nodes; Reed-Sternberg cells are often found on microscopic analysis
45
HIV - Human Immunodeficiency Virus
Virus that causes AIDS Retro viruses are a class of viruses that have RNA instead of DNA as their genetic material
46
Kaposi Sarcoma
Malignant lesion associated with AIDS; arises from the lining of capillaries and appears red , purple, brown or black skin nodules. Kaposi sarcoma is caused by human herpies virus 8
47
Non- Hodgkin Lymphoma
Group of malignant tumors involving lymphoid tissue. ex follicular lymphoma and large cell lymphoma
48
opportunitistic Infections
Infectious diseases associated with AIDS; the occur because of HIV lowers the bodys resistance and allows infection by bacteria and parasites that normally are eaisly contained
49
Protease Inhibitor
Drug that treats AIDS by Blocking the production of protease, a proteolytic emzyme that helps create new viral piecew for HIV other antiretroviral drugs are entry inhibitors and integrase inhibitors
50
Reverese Transcriptase Inhibitor (RTI)
Drug that treats AIDS by blocking reverese transcriptase, an enzyme needed to make copies of HIV
51
