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 secrete antibodies. The B refers to the bursa of Fabricius, an organ in birds in which B-cell differentiation and growth were first noted to occur.
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. Examples are interferons, interleukins, and colony-stimulating factors (G-CSF and GM-CSF).
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. Examples are vaccines, dendritic cells, monoclonal antibodies, and donor lymphocyte infusion.
inguinal node
One of several lymph nodes in the groin region (area where the legs join the trunk of the body).
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 specific components of the immune response.
interstitial fluid
Fluid in the spaces between cells. This fluid becomes 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 persons 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
Lymphocyte 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 ducts
Large lymph vessel in the chest that receives lymph from below the diaphragm and from the left side of the body above the diaphragm;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 that caused the disease cow pox to produce immunity to smallpox.
Weakened or killed microorganisms administered to induce immunity to infection or disease.
