Vocabulary:

interferons
Vocabulary:

Proteins (cytokines) that stimulate the growth of B and T lymphocytes
Vocabulary:

Vocabulary:

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

interstitial fluid
Vocabulary:

Thin, watery fluid found within lymphatic vessels and collected from tissues throughout the body.
Vocabulary:

lymph
Vocabulary:

Tiniest lymphatic vessels
Vocabulary:

lymph capillaries
Vocabulary:

Lymph nodes, spleen, and thymus gland
Vocabulary:

lymphoid organs
Vocabulary:

A collection of stationary solid lymphatic tissue along lymph vessels
Vocabulary:

lymph node
Vocabulary:

Carrier of lymph throughout the body; empties lymph into veins in the upper part of the chest
Vocabulary:

lymph vessel
Vocabulary:

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

macrophage
Vocabulary:

Lymph nodes in the area between the lungs in the thoracic (chest) cavity
Vocabulary:

mediastinal nodes
Vocabulary:

Antibody produced in a laboratory to attack antigens and to destroy cells. It is useful in immunotherapy
Vocabulary:

monoclonal antibody
Vocabulary:

Protection that an individual inherits to fight infection
Vocabulary:

natural immunity
Vocabulary:

Lymphocyte that produces and secretes antibodies. It originates from B lymphocytes
Vocabulary:

plasma cell
Vocabulary:

Large lymphatic vessel in the chest that receives lymph from the upper right part of the body
Vocabulary:

right lymphatic duct
Vocabulary:

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

spleen
Vocabulary:

Lymphocyte that inhibits the activity of B and T lymphocytes. Also called a Treg (regulatory T cell)
Vocabulary:

suppressor T cell
Vocabulary:

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
Vocabulary:

T cell (T lymphocyte)
Vocabulary:

The ability of T lymphocytes to recognize and accept the body's own antigens as "self" or friendly.
Vocabulary:

tolerance
Vocabulary:

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
Vocabulary:

thoracic duct

Mass of lymphatic tissue int he back of the oropharynx
Vocabulary:

tonsils
Vocabulary:

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