Lymphatic And Immune Systems - Ch. 14 Chab. Lom

Front 1

acquired immunity

Back 1

Formation of antibodies and lymphocytes after exposure to an antigen.

Front 2

adenoids

Back 2

Masses of lymph tissue in the nasopharynx.

Front 3

antibody

Back 3

Protein produced by lymphocytes that destroys antigens.

Front 4

axillary node

Back 4

One of 20 to 30 lymph nodes in the armpit (underarm).

Front 5

B cell

Back 5

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.

Front 6

cell-mediated immunity

Back 6

An immune response involving T-cell lymphocytes; antigens are destroyed by direct action of cells,as opposed to antibodies.

Front 7

cervical node

Back 7

One of many lymph nodes in the neck region

Front 8

cytokine

Back 8

Protein that aids cells to destroy antigens. Examples are interferons, interleukins, and colony-stimulating factors (G-CSF and GM-CSF).

Front 9

cytotoxic cell

Back 9

T-cell lymphocyte that directly kills foreign cells; also called T8 cell.

Front 10

dendritic cell

Back 10

Cell that captures antigens and presents them to T cells.

Front 11

helper T cell

Back 11

Lymphocyte that aids B cell in recognizing antigens and stimulating antibody production; also called T4 cell.

Front 12

humoral immunity

Back 12

Immune response in which B cells transform into plasma cells and secrete antibodies.

Front 13

immune response

Back 13

The body's capacity to resist all types of organisms and toxins that can damage tissue and organs; immunity

Front 14

immunoglobulins

Back 14

Antibodies (gamma globulins) such as IgA, IgE, IgG, IgM, and IgD that are secreted by plasma cells in humoral immunity.

Front 15

immunotherapy

Back 15

Use of immunologic knowledge and techniques to treat disease. Examples are vaccines, dendritic cells, monoclonal antibodies, and donor lymphocyte infusion.

Front 16

inguinal node

Back 16

One of several lymph nodes in the groin region (area where the legs join the trunk of the body).

Front 17

interferons

Back 17

Antiviral proteins (cytokines) secreted by T cells; they also stimulate macrophages to ingest bacteria.

Front 18

interleukins

Back 18

Proteins (cytokines) that stimulate the growth of B- or T-cell lymphocytes and activate specific components of the immune response.

Front 19

interstitial fluid

Back 19

Fluid in the spaces between cells. This fluid becomes lymph when it enters lymph capillaries.

Front 20

lymph

Back 20

Thin, watery fluid found within lymphatic vessels and collected from tissues throughout the body. Latin, lympha means "water".

Front 21

lymph capillaries

Back 21

Tiniest lymphatic vessels.

Front 22

lymphoid organs

Back 22

Lymph nodes, spleen, and thymus gland

Front 23

lymph node

Back 23

Stationary lymph tissue along lymph vessels.

Front 24

lymph vessel

Back 24

Carrier of lymph throughout the body;lymph vessels empty lymph into veins in the upper part of the chest.

Front 25

macrophage

Back 25

Large phagocyte found in lymph nodes and other tissues of the body.

Front 26

mediastinal node

Back 26

One of many lymph nodes in the area between the lungs in the thoracic (chest) cavity.

Front 27

monoclonal antibody

Back 27

An antibody produced in a laboratory to attack antigens.It is useful in immunotherapy and cancer treatment.

Front 28

natural immunity

Back 28

A persons own genetic ability to fight off disease

Front 29

natural killer (NK) cell

Back 29

Lymphocyte that recognizes and destroys foreign cells (viruses and tumor cells) by releasing cytotoxins.

Front 30

plasma cell

Back 30

lymphoid cell that secretes an antibody and originates from B-cell lymphocytes.

Front 31

right lymphatic duct

Back 31

Large lymph vessel in the chest that receives lymph from the upper right part of the body.

Front 32

spleen

Back 32

Organ near the stomach that produces,stores, and eliminates blood cells.

Front 33

suppressor T Cell

Back 33

Lymphocyte that inhibits the activity of B- and T- cell lymphocytes.

Front 34

T cell

Back 34

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.

Front 35

thoracic ducts

Back 35

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.

Front 36

thymus gland

Back 36

Organ in the mediastinum that produces T-cell lymphocytes and aids in the immune response.

Front 37

tonsils

Back 37

Masses of lymph tissue in the back of the oropharynx.

Front 38

toxin

Back 38

Poison; a protein produced by certain bacteria, animals, or plants.

Front 39

vaccination

Back 39

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.

Front 40

vaccine

Back 40

Weakened or killed microorganisms administered to induce immunity to infection or disease.
