Chapter 13: The Lymphatic and Immune System - 25 Tough Terms Flashcards
Resistance to a disease acquired naturally or developed by previous exposure or vaccination (injection of antigen)
Acquired active immunity
Inoculation against disease or poison, using antitoxins or antibodies from or in another person or another species
Acquired passive immunity
Specialized protein that fights disease; immunoglobin
Antibody
Any substance that can provoke an immune response
Antigen
Antibodies directed against a particular disease or poison, given when immediate immunity is required (snake bite, this is an example of acquired passive)
Antitoxin
Lymphocyte that manufactures antibodies
B cells
Types of active acquired immunity
humoral immunity (AA1 type 1) cell mediated immunity (AAI type 2)
Resistance to disease mediated by T cells
Cell mediated immunity
T cell that helps in destruction of infected cells throughout the body
Cytotoxic cell
preparation of collected antibodies given to prevent or lessen certain diseases
Gamma globulin
T cell that stimulates the immune response
Helper cell
Resistance to disease provided by plasma cells and antibody production
Humoral immunity
Protein produced by T cells and other cells; destroys disease-causing cells with its antiviral properties
Interferon
Protein produced by T cells; helps regulate immune system
Interleukin
Inherent resistance to disease found in species, race, family group, or certain individuals
Natural immunity
Specialized lymphocyte that produces immunoglobulins
Plasma cell
T cell that suppresses B cells and other immune cells
Suppressor
Hormone secreted by the thymus gland that aids in distribution of thymocytes and lymphocytes
Thymosin
Specialized white blood cells that receive markers in the thymus, are responsible for cellular immunity, an assist with humoral immunity
T Cells
Test primarily used to check for antibodies to HIV in serum
Western blot
Test used to screen blood for the presence fo antibodies to different viruses or bacteria
Enzyme-linked immunosorbent assay (EIA, ELISA)
Production of IgE antibodies agains an allergen
Allergy
Lymphoma with malignant cells that resemble hitiocytes
Histiocytic lymphoma
Acute infections disease caused by the Epstein-Barr virus
Infections mononucleosis
Cancer of the lymph nodes with some cells resembling healthy cells and spreading in a diffuse pattern
non-Hodgkin’s lymphoma
Inflammatory condition with lesions on the lymph nodes and other organs
Sarcoidosis
Immunoglobin effective agains bacteria, viruses, and toxins
IgG
Immunoglobin common in exocrine gland secretions like breast milk tears nasal fluid gastric juice
IgA
Immunoglobin that develops in blood plasma in response to certain antigens within the body or from foreign sources
First produced after infections
IgM
Immunoglobin important in B cell activation, helps immunity by transforming itself into a plasma cell
IgD
Immunoglobin that appears in glandular secretions and is associated with allergic reactions
IgE
