|
|
Term
|
Definition
| Antibodies (gamma globulins) such as IgA, IgE, IgG, IgM, and IgD that are secreted by plasma cells in humoral activity. |
|
|
Term
|
Definition
| Use of immunologic knowledge and techniques to treat or prevent disease. Examples are inoculation wiht vaccines and monoclonal antibody therapy |
|
|
Term
|
Definition
| One of several lymph nodes in the groin region |
|
|
Term
|
Definition
| Antiviral proteins (cytokines) secreted by T cells; they also stimulate macrophages to ingest bacteria |
|
|
Term
|
Definition
| Proteins (cytokines) that stimulate the growth of B or T lymphocytes and activate specific components of the immune response |
|
|
Term
|
Definition
| Fluid in the spaces between cells. This fluid becomes lymph when it enters lymph capillaries |
|
|
Term
|
Definition
| Cytotoxic T cell lymphocyte that recognizes and destroys foreign cells (viruses and tumor cells) |
|
|
Term
|
Definition
| Clear watery fluid found within lymphatic vessels and collected from tissues throughout the body |
|
|
Term
|
Definition
| Tiniest lymphatic vessels |
|
|
Term
|
Definition
| Lymph nodes, spleen, and thymus gland |
|
|
Term
|
Definition
| Stationary solid lymphatic tissue along lymph vessels |
|
|
Term
|
Definition
| Carrier of lymph throughout the body; lymphatic vessels empty lymph into veins in the upper part of the chest |
|
|
Term
|
Definition
| Large phagocyte found in lymph nodes and other tissues of the body |
|
|
Term
|
Definition
| Any of the many lymph nodes in the area between the lungs in the thoracic cavity |
|
|
Term
|
Definition
| Antibody produced in a laboratory to attack antigens. It is useful in immunotherapy and cancer treatment |
|
|
Term
|
Definition
| An individual's own genetic ability to fight off disease |
|
|
Term
|
Definition
| Lymphoid cell that secretes an antibody and originates from B lymphocytes |
|
|
Term
|
Definition
| Large lymphatic vessel in the chest that receives lymph from the upper right part of the body |
|
|
Term
|
Definition
| Organ near the stomach that produces, stores, and eliminates blood cells |
|
|
Term
|
Definition
| Lymphocyte that inhibits the activity of B and T lymphocytes |
|
|
Term
|
Definition
| Lymphocyte that originates in the bone marrow but matures in the thymus gland; it acts directly on antigens to destroy them or produce chemicals (cytokines) such as interferons and interleukins that are toxic to antigens |
|
|
Term
|
Definition
| In the thymus, T lymphocytes learn to recognize and accept the body's own antigens as "self" or friendly |
|
|
Term
|
Definition
| Large lymphatic 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 |
|
