chapter 14

formation of antibodies and lymphocytes after exposure to an antigen

depression or suppression of the immune system after exposure to the human immunodeficiency virus marked by opportunistic infections, secondary neoplasms and neurologic problems

masses of lymphatic tissues in the nasopharynx

substance capable of causing a specific hypersensitivity in a body; an antigen

abnormal hypersensitivity acquired by exposure to an antigen

exaggerated or unusual hypersensitivity to foreign protein or other substance

protein produced in the bloodstream by lymphocytes in response to a specific antigen, such as a bacterium or toxin. antibodies destroy or weaken antigens

intense allergic reaction, influence by hereditary tendency or predisposition

chronic disabling disease caused by the abnormal production of antibodies to normal body tissues, multiple sclerosis and lupus erythematosus are examples

lymph node under the arm

a lymphocyte that originates in bone marrow and transforms into a plasma cell to secrete antibodies

helper T cells that carry the CD4+ protein antigen on their surface

type of immune response that involves Tcell lymphocytes. these lymphocytes act directly on antigens to destroy them

lymph node in the neck

protein that aids ells to destory antigens.

T-cell lymphocyte that directly kills foreign cells

a type of macrophage that captures antigens and presents them to cells for destruction

test to detect anti-HIV antibodies in blood. this is a screening test for AIDS

lymphocyte that aids a B-cell lymphocyte in recognizing antigens and stimulating antibody production

malignant tumor of lymphatic tissue in the spleen the lymph nodes

virus that causes AIDS

type of immune response in which a B cell lymphocyte transforms into a plasma cell and secretes antibodies

abnormal condition characterized by an exaggerated response of the immune system to an antigen

syndrome of spleen enlargement and destruction of red blood cells

the bodys capability to resist foreign organisms and toxins that can damage tissue and organs

laboratory test that separates immunoglobulins

antibodies secreted by B-cell lymphocytes

blocking or turning off the normal immune response

use of immunologic techniques to treat disease

lymph node in the groin region

anti-viral proteins secreted by lymphocytes

proteins that stimulate the immune system including B and T cell lymphocytes

fluid that fills the spaces in between cells

malignant tumor of skin and connective tissue; associated with AIDS

fluid that circulates within lymph vessels and lymph nodes

tiny lymph vessels that carry lymph through the body

mass of stationary lymphatic tissue along the path of lymph vessels

carry lymph throughout the body

inflammation of lymph nodes

disease of lymph nodes

abnormal collection of fluid in tissue spaces caused by obstruction of lymph vessels and backflow of lymph

white blood cells that develop primarily in lymph nodes and the spleen and fight against foreign organisms

deficiency of lymphocytes

increase in numbers of lymphocytes in the bloodstream

organs containing and derived from lymphatic tissue; spleen, thymus gland, and lymph nodes

malignant tumor of lymph nodes and lymphatic tissue

formation of lymphocytes

large phagocyte found in lymphatic tissues and connective tissues; derived from a monocyte

lymph node in the mediastinum

antibody produced in a laboratory to attack specific antigens

malignant tumor of bone marrow cells

persons own genetic ability to figh toff disease. includes phagocytes and lymphocytes such as natural killer cells

lymphocyte that recognizes and destorys foreign cells by releasing proteins called cytokines

malignant tumor cells found in lymph nodes and spleen

infectious diseases associated with AIDS toxoplasmosis, tuberculosis, herpes simplex, and pneumocytosis carinii pneumonia

B cell lymphocyte that secretes antibodies

drug used to treat AIDS by blocking production or protease, an enzyme that helps HIV to reproduce

virus that makes copies of itself using the hosts cells DNA a process that is the reverse of the normal replication mechanism in cell HIV is a retrovirus

drugs used to treat AIDS by blocking an enzyme needed to make copies of HIV

receives lymph from the right side of the body and empties lymph into a vein in the neck

organ adjacent to the stomach that produces, stores, and eliminates blood cells

removal of the spleen

enlargement of the spleen

lymphocyte that inhibits the activity of B and T cell lymphocytes

lymphocyte originating in the thymus gland and destroys antigens by direct action or production of cytokines such as interferons and interleukins

large lymphatic vessel in the upper chest

removal of the thymus gland

malignant tumor of the thymus gland

lymphoid organ in the mediastinum that produces T cell lymphocytes and aids in the immune response

masses of lymphatic tissues on either side of the back of the mouth

pertaining to a toxin, which is a poison or harmful substance

poison or harmful substance

introduction of vaccine to produce immunity. it is a type of acquired immunity

weakend or dead antigen is administered to induce production of antibodies resulting in immunity

measures the amount of HIV in the blood stream

weight loss and decrease in muscle strength , appetite, and mental activity that occurs with aids

specific test to detect presence of anti- HIV antibodies in the bloodstream
