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
Q

Lymph Organs

A

Lymph Nodes, Spleen, and tymus gland. Tonsils and adenoids are other examples of lymphoid organs

26
Q

Lymph Vessels

A

Carrier of Lymph thoughtout the body; lymphatic vessels empty lymph into veins in the upper part of chest

27
Q

Macrophage

A

Large phagocyte found in lymph nodes and other tissue of the body.
Phag/o means to wat or swallow

27
Q

Mediastinal Nodes

A

Lymph nodes in the area between the lungs in the chest cavity

28
Q

Paraaortic Nodes

A

Lymph nodes near the aorta in the lumbar(waist) area of the body

28
Q

Monoclonal Antibody

A

anibodie produced in a lab to attack antigens and to destroy cells; useful immunotherapy

28
Q

Natural Immunity

A

protection that an individual is born with to fight infection such as neutrophil, monocytes, Macrophages, and NK cells. its not antigen specific

28
Q

Plasma cell

A

Lymphocyte that secretes anitbodies. it natures from B lymphocytes

29
Q

Mesenteric Nodes

A

Lymph nodes in the mesentery (intestinal region)

30
Q

Right lymphatic Duct

A

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
Q

Spleen

A

Organ in the upper left quadrant of the abdomen that destroys worn-out red blood cells, activates lymphocytes and stores blood

32
Q

Suppressor T cell (treg)

A

Lymphocyte that inhibits the activity of B and T cells ( Regulatory T cell)

33
Q

T cell (T lymphocyte)

A

Lymphocyte that acts directly on antigens to destroy them or produce chemicals (cytokine) such as interferons and interleukins that are toxic

34
Q

Thoratic Duct

A

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
Q

Thymus Gland

A

Lymphoid organ in the mediastainum that conditions T cells to reast to foreign cells and aids in the immune response

36
Q

Tolerance

A

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
Q

Tonsils

A

Masses of lymphatic tissue in the back of the oropharynx

38
Q

Toxins

A

Poison; a protein produced by certain Bacteria, animals or plants

39
Q

Vaccination

A

Exposure of an individual to a foreign protein(antigen) that provokes an immune response

40
Q

Vaccine

A

Weakened or dead antigen is given to induce production of antibodies. this results in adaptive immunity

41
Q

Anaphylaxis

A

Exaggerated or unsusalt hypersensitivity to foreign proteins or other substances

41
Q

Allergen

A

Substance capable Of causing a specific hypersensitivity reaction; a Type of antigen

42
Q

Atopy

A

Hypersensitive or allergic state involving an inherited predisposition. from the greek work Atopia means strangeness

43
Q

CD4 + cells

A

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
Q

Hodgkin Lymphoma

A

Malignant tumor of Lymphoid tissue in spleen and lymph nodes; Reed-Sternberg cells are often found on microscopic analysis

45
Q

HIV - Human Immunodeficiency Virus

A

Virus that causes AIDS Retro viruses are a class of viruses that have RNA instead of DNA as their genetic material

46
Q

Kaposi Sarcoma

A

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
Q

Non- Hodgkin Lymphoma

A

Group of malignant tumors involving lymphoid tissue. ex follicular lymphoma and large cell lymphoma

48
Q

opportunitistic Infections

A

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
Q

Protease Inhibitor

A

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
Q

Reverese Transcriptase Inhibitor (RTI)

A

Drug that treats AIDS by blocking reverese transcriptase, an enzyme needed to make copies of HIV

51
Q

Wasting Syndrome

A

weight loss and decrease in muscular strenghth appitite and mental activity associated with AIDS
