Chap 14 MedTerm

Lymphatic and immune systems

interstitial fluid fluid in the spaces between the cells
cervical (neck)
axillary (armpit)
mediastinal (chest)
mesenteric (intestinal)
inguinal (groin)
Dendrite cells antigen- presenting cells, shows T and B cells what to attack
B- Cells (Humoral Immunity) lymphocytes that transform into plasma cells and secret antibodies called (immunoglobulins)
T- Cells (Cell Mediated Immunity) attach to antigens that help other cells respond to antigens
Humoral An immune response in which B cells transform into plasma cells and secrete antibodies is known as
Cell Mediated Immunity an immune response in which T- Cells destroy is called
B- Cells Humoral Immunity or Antibody Mediated Immunity
T- Cells Cell Mediated or T-8 killer
T4- Helper cells assist B cells in making antibodies and they stimulate T cells to attack antigens
adaptive immunity the ability to recognize and remember specific antigens (humoral (B Cell) and cell mediated immunity (T Cell)
cytotoxic cells Lymphocyte that directly kills antigens, called T- cell, T-8 killer cells
immunoglobulins antibodies (proteins), IgA, IgE, IgM, and IgD; secreted by plasma cells (mature B cells) in response to the presence of an antigen
interferons antiviral proteins secreted by T cells
lymph thin, watery fluid within lymphatic vessels and collected from tissues throughout the body
lymph node stationary solid lymphatic tissue along lymph vessels; contains cells (lymphocytes and marcophages) that fight infection
macrophage large phagocyte found in lymph nodes and other tissues of the body
plasma cells transformed B cells that secrete antibodies
spleen organ in the left upper quadrant of the abdomen that destroys wornout red blood cells, activates lymphocytes, and stores blood
thymus gland toxin lymphoid organ in the mediastinum that conditions T cells to react to foreign cells and aids in the immune response
vaccine/vaccination weakened or killed microorganisms, toxins, or other given to induce immunity to infection or disease
lymphedema swelling of tissues due to interstitial fluid accumulation
lymphedema can be the result of surgery such as mastectomy (removal of breast)
vaccination introduction of altered antigens to produce an immune response
AIDS acquired immunodeficiency syndrome
candidiasis (infections associated with aids) yeast like fungus; mouth, skin, intestinal, tract, and vagina, overgrows, causing, infection of the mouth, respiratory tract and skin
cryptococcal infection yeast like fungus; lung brain, and blood infections
cryptomegalovirus (cmv) infection viruses causes enteritis and retinitis (inflammation of the retina at the back of the eye )
herpes simplex viral infection causes small blisters on the skin of the lips or nose or on the genitals
histoplasmosis fungal infection caused by inhalation by dust contaminated with fever, chills and lung infection
hypersensitivity undesirable reactions produced by the normal immune system; allergy
allergy abnormal hypersensitivity acquired by exposure to an antigen
rhinitis hay fever
rhinorrhea the nasal cavity is filled with excess mucus fluid
anaphylaxis exaggerated hypersensitivity reaction
urticaria/ hives raised, itchy areas of the skin that are signs of an allergic reaction
angioedema acute swelling of the lips and/or eyes resulting from an allergic response to medication
splenomegaly abnormal enlargement of the spleen
toxic poisons (antigens)/ pertaining to poison
normal t helper lymphocyte cell count 1200
what is clinical AIDS? T4 cell lymphocytes < 200 and HIV positive
what is HIV infection? T4 cell lymphocyte count > 200 and HIV positive
Opportunistic infections candidiasis is yeast like fungus---- infectious disease associated with AIDS; they occur because HIV infection lowers body's resistance and allows infection by bacteria and parasites that normally are easily contained
cytomegalovirus herpesvirus group
lymphadenitis inflammation of the lymph nodes
herpes painful fluid filled blisters
toxoplasmosis an injection caused by a single cell parasite named toxoplasma gondii
toxoplasma gondii may invade tissues and damage the brain, fetus and newborn
PPD purified protein derivative (skin test for TB)
PCP pneumocystis pneumonia - opportunistic AIDS related infection
hemoptysis spitting up blood
kaposi's sarcoma malignant lesion associated with AIDS; arises from the lining of capillaries and appears as red, purple, brown, or black skin nodules
kaposi's sacroma purplish, reddish, bluish spots
KS kaposi sacroma
Hodgkin's disease malignant tumor of the lymph nodes in spleen marked by reed sternberg cell identified in lymph nodes
lympopoesis formation of lymph
lymphoma a tumor of the lymphoid tissue
protease inhibitors most prescribed types of HIV drugs
ELISA screening test screening test to detect anti HIV antibodies in the blood stream
ELISA enzyme linked immunosorbent assay
Western Blot Test confirmatory,test uses electrophoresis to separate specific viral proteins
hypertrophy hyPERtrophy
