Chapter 22: Lymphatic System and Immunity Flashcards
Adenitis
Inflammation of the adenoid (pharyngeal tonsil).
Allograft
Transplant between compatible recipient and donor of the same species.
Autograft
A transplant of tissue that is taken from the same person.
Burkitt Lymphoma
A malignant cancer of B lymphocytes.
Chronic Fatigue Syndrome
A complicated disorder most often characterized by extreme fatigue that does not improve with rest, and which may worsen with physical activity.
Congenital Thymic Aplasia
Congenital (present at birth) absence of the thymus and parathyroid glands and a deficiency of immunity.
Coombs Test
A medical test to detect antibodies or complement in the blood.
Dermatomyositis
An autoimmune disease characterized by inflammation of the skin and muscles.
Eczema
A genetic inflammatory skin disorder, often with crusts, papules, and leaky eruptions.
Hodgkin Lymphoma
A malignant lymphoma affecting lymph nodes and lymph organs.
Host Versus Graft Disease
A pathological condition in which cells from the transplanted tissue of a donor initiate an immune response, attacking the cells and tissue of the recipient.
Hybridoma
A tissue culture composed of cancer cells fused to lymphocytes to mass produce a specific antibody.
Immunology
Branch of biomedicine concerned with the structure and function of the immune system.
Infectious Mononucleosis
An acute disease caused by the Epstein-Barr virus, producing fever, swelling of the lymph nodes, sore throat, and increased lymphocytes in the bloodstream.
Latex Allergy
Hypersensitivity to products made of the sap of the rubber plant.
Polymyositis
An autoimmune disease characterized by inflammation and atrophy of muscles.
Sentinel Node
The first lymph node to receive drainage from a tumor. It is used to determine if there is lymphatic metastasis in some types of cancer.
Splenomegaly
Enlargement of the spleen.
Systemic Lupus Erythematosus (SLE)
An autoimmune disease in which a person’s immune system attacks and injures its own organs and tissues in virtually every system of the body.
Xenograft
A transplant that is made between two different species.
Abscess
A localized collection of pus within a damaged tissue.
Adhesion
The fusion of two mesenterial layers after damage or irritation of their opposing surfaces; this process restrict relative movement of the organs involved; the binding of a phagocyte to its target.
Agglutination
The aggregation of red blood cells due to interactions between surface antigens and plasma antibodies.
AIDS (Acquired Immunodeficiency Syndrome)
A disease caused by the human immunodeficiency virus (HIV); characterized by the destruction of helper T cells and a resulting severe impairment of the immune response.
Anaphylaxis
A hypersensitivity reaction due to the binding of antigens to immunoglobulins (IgE) on the surfaces of mast cells; the release of histamine serotonin, and prostaglandins by mast cells then causes widespread inflammation; a sudden decrease in blood pressure may occur, producing anaphylactic shock.
Antibody
A globular protein produced by plasma cells that will bind to specific antigens and promote their destruction or removal form the body.
