Lymphatic and immune systems
| Question | Answer |
|---|---|
| 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 |
