Language of Medicine Chap 14
production of antibodies and lymphocytes after exposure to an antigen.
Mass of lymphatic tissue in the nasopharynx
Protein produced by B cell lymphocytes to destroy antigens
substance that the body recognizes as foreign; evokes an immune response. Most are proteins or protein fragments
lymph nodes in the armpit
Lymphocyte that originates in the bone marrow and transforms into a plasma cell to secrete antibodies.
Lymph nodes in the neck region
Proteins in the blood that help antibodies and T-cells kill their target.
Proteins that aid and regulate the immune response
Cytotoxic T cell
T lymphocyte that directly kills foreign cells
Specialized macrophage that digests foreign cells and helps B and T cells to mark antigens for destruction.
Helper T cell
Lymphocyte that aids B cells and cytotoxic T cells in recognizing antigens and stimulates antibody production
Body's ability to resist foreign organisms and toxins. This includes natural and acquired.
Antibodies that are secreted by plasma cells in response to the presence of an antigen
Use of immune cells, antibodies or vaccines to treat of prevent disease.
Lymph nodes in the groin region
Proteins (cytokines) secreted by T cells to aid and regulate the immune response
Proteins (cytokines) that stimulate the growth of B and T lymphocytes
Fluid in the spaces between the cells. This fluid becomes lymph when it enters lymph capillaries.
Thin, watery fluid found within lymphatic vessels and collected from tissues throughout the body.
Tiniest lymphatic vessels
Lymph nodes, spleen, and thymus gland
A collection of stationary solid lymphatic tissue along lymph vessels
Carrier of lymph throughout the body; empty lymph into veins in the upper part of the chest.
Large phagocyte found in lymph nodes and other tissues
Lymph nodes in the area between the lungs in the thoracic cavity
Antibody produced in a laboratory to attack antigens and to destroy cells
Protection that an individual inherits to fight infection.
Lymphocyte that produces and secretes antibodies.
Right Lymphatic Duct
Large lymphatic vessel in the chest that receives lymph from the upper right part of the body.
Organ near the stomach that produces, stores and eliminates blood cells.
Suppressor T cell
Lymphocyte that inhibits the activity of B and T lymphocytes
Lymphocyte that originates in the bone marrow but matures in the thymus gland; works by destroying antigens or producing chemicals which are toxic to antigens.
The ability of T lymphocytes to recognize and accept the body's own antigens as self or friendly.
Large Lymphatic vessel in the chest that receives lymph from below the diaphragm and from the left side of the body above the diaphragm.
Organ in the mediastinum that conditions T lymphocytes to react to foreign cells and aids in the immune response.
Mass of lymphatic tissue in the back of the oropharynx
Exposure of an individual to a foreign protein that provokes an immune response. The response will destroy any cell that possesses the antigen on its surface and will protect against infection.
Weakened or killed microorganisms, toxins, or other proteins given to induce immunity to infection or disease.
Group of clinical signs and symptoms associated with suppression of the immune system and marked by opportunistic infections, secondary neoplasms, and neurologic problems
Abnormal hypersensitivity acquired by exposure to an antigen
Malignant tumor of lymph nodes and lymph tissue
Malignant tumor of lymphoid tissue in the spleen and lymph nodes
B cell lymphomas
Malignant tumor of bone marrow cells
Malignant tumor of the thymus gland
Substance capable of causing a specific hypersensitivity reaction in the body
Exaggerated or unusual hypersensitivity to foreign protein or other substances
Hypersensitive or allergic state involving an inherited predisposition
helper T cells that carry the CD4 protein antigen on their surface. HIV binds to CD4 and infects and kills T cells bearing the protein
virus that causes aids
Malignant lesion associated with AIDS; arises from the lining of capillaries and appears as red, purple, brown, or black skin nodules
infectious diseases associated with AIDS; they occur because HIV infection lowers the body's resistance and allows infection by bacteria and parasites that normally are easily contained
drug that treats AIDS by blocking the production of protease, a proteolytic enzyme that helps to create new viral pieces for HIV
Reverse Transcriptase Inhibitor
drug that treats AIDS by blocking reverse transcriptase, an enzyme needed to make copies of HIV
weight loss, decrease in muscular strength, appetite, and mental activity
CD4+ cell count
Measures the number of CD4+ T cells in the bloodstream of patients with AIDS
Screening test to detect anti-HIV antibodies in the bloodstream
Test the separates immunoglobulins
Viral Load Test
Measurement of the amount of AIDS virus in the bloodstream
