  • Front
  • Back
acquired immunity
formation of antibodies and lymphocytes after exposure to an antigen
masses of lymph tissue in the nasopharynx
protein produced by lymphocytes that destroys antigens
axillary node
one of 20 to 30 lymph nodes in the armpit (underarm)
B cell
lymphocyte that originates in the bone marrow and transforms into a plasma cell to secret antibodies.
cell-mediated immunity
an immune response involving T-cell lymphocytes; antigens are destroyed by direct action of cells, as opposed to antibodies
cervical node
one of many lymph nodes in the neck region
protein that aids cells to destroy antigens
cytotoxic cell
T-cell lymphocyte that directly kills foreign cells; also called T8 cell
dendritic cell
cell that captures antigens and presents them to T cells
helper T cell
lymphocyte that aids B cell in recognizing antigens and stimulating antibody production; also called T4 cell
humoral immunity
immune response in which B cells transform into plasma cells and secrete antibodies
immune response
the body's capacity to resist all types of organisms and toxins that can damage tissue and organs; immunity
antibodies (gamma globulins) such as IgA, IgE, IgG, IgM, and IgD that are secreted by plasma cells in humoral immunity
use of immunologic knowledge and techniques to treat disease
inguinal node
one of several lymph nodes in the groin region
antiviral proteins (cytokines) secreted by T cells; they also stimulate macrophages to ingest bacteria
proteins (cytokines) that stimulate the growth of B- or T-cell lymphocytes and activate specifric components of the immune system
interstitial fluid
fluid in the spaces between cells. This fluid becoms lymph when it enters lymph capillaries
Thin, watery fluid found within lymphatic vessels and collected from tissues throughout the body. Latin, lympha, means "water."
lymph capillaries
tiniest lymphatic vessels
lymphoid organs
lymph nodes, spleen, and thymus gland
lymph node
stationary lymph tissue along lymph vessels
lymph vessel
carrier of lymph throughout the body; lymph vessels empty lymph into veins in the upper part of the chest
large phagocyte found in lymph nodes and other tissues of the body
mediastinal node
one of many lymph nodes in the area between the lungs in the thoracic (chest) cavity
monoclonal antibody
an antibody produced in a laboratory to attack antigens. It is useful in immunotherapy and cancer treatment
natural immunity
a person's own genetic ability to fight off disease
natural killer (NK) cell
lymphocyte that recognizes and destroys foreign cells (viruses and tumor cells) by releasing cytotoxins
plasma cell
lymphoid cell that secretes an antibody and originates from B-cell lymphocytes
right lymphatic duct
large lymph 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-cell lymphocytes
T cell
lymphocytes formed in the thymus gland; it acts directly on antigens to destroy them or produce chemicals such as interferons and interleukins that are toxic to antigens
thoracic duct
large lymph vessel in the chest that r eceives lymph from below the diaphragm and from the left side of the body above the diaphragam; it empties the lymph into veins in the upper chest
thymus gland
organ in the mediastinum that produces T-cell lymphocytes and aids in the immune response
masses of lymph tissue in the back of the oropharynx
poison; a protein produced by certain bacteria, animals or plants
introduction of altered antigens (viruses or bacteria) to produce an immune response and protection against disease. The term comes from the Latin "vacca," meaning "cow," and was used when the first inoculations were given with organisms thatr caused the disease cow pox to produce immunity to smallpox
weakened or killed microorganisms administered to produce immunity to infection or disease
lymph node
thymus gland
again, new
autoimmune disease
chronic, disabling disease caused by abnormal production of antibodies to normal tissues
antibodies - IgA, IgE, IgG, IgM, IgD
formation of lymph cells
swelling of tissues due to interstitial fluid accumulation
deficiency of lymph cells
abnormal condition of the lymph cells
resembling lymph
disease condition of the lymph node
inflammation of the lymph node
enlargement of the spleen
removal of the spleen
syndrome marked by enlargement of the spleen and associated with anemia, leukopenia, and thrombocytopenia
tumor of the thymus gland
removal of the thymus gland
pertaining to poison
anew protection
interstitial fluid
fluid that lies between cells and becomes lymph as it enters lymph capillaries
pertaining to standing or positioned
substance capable of causing a specific hypersensitivity in the body; a type of antigen
exaggerated or unusual hypersensitivity to foreign protein or other substance
hypersensitive or allergic state involving an inherited predisposition. From the Greek word atopia, which means strangeness
CD4 + lymphocytes
helper T cells that carry the CD4+ protein antigen on their surface. HIV binds to CD4+ and infects and kills T cells bearing this protein
Hodgkin disease
malignant tumor or lymph tissue in spleen and lymph nodes; Reed-Sternberg cell is often found on microscopic analysis
human immunodeficiency virus (HIV)
virus (retrovirus) that causes AIDS
Kaposi sarcoma
Malignant (cancerous) condition associated with AIDS; arises from the lining of capillaries and appeaars as bluish-red skin nodules
opportunistic infections
infectious diseases associated with AIDS; they occur because AIDS lowers the body's resistance and allows infection by bacteria and parasites that normally are easily contained
non-Hodgkin lymphoma
group of malignant tumors involving lymphoid tissue. Examples are follicular lymphoma and large cell lymphoma
protease inhibitor
drug that treats AIDS by blocking the production of protease, a proteolytic enzyme that helps to create new viral pieces for HIV
RNA virus that makes copies of itself by using the host cell's DNA; this is in reverse (retro-) fashion because the regular method is for DNA to copy itself onto RNA. A retrovirus (like HIV) carries an enzyme, called reverse transcriptase, that enables it to reproduce within the host cell
reverse transcriptase inhibitor
drug that treats AIDS by blocking reverse transcriptase, an enzyme needed to make copies of the HIV virus
ELISA test
test to detect anti-HIV antibodies
test that separates immunoglobulins (IgG, IgM, IgE, IgA, IgD)
CT scan
computerized x-ray imaging in the transverse plane (computed tomography)
