Chapter 14 - Lymphatic/Immune Flashcards
Adaptive Immunity
Ability to recognize and remember specific antigens and attack them
Adenoids
Mass of lymphatic tissue in the nasopharynx
Antibody
Protein produced by B cells that destroy antigens
Antigen
Substance that the body recognizes as foreign and starts an immune response
Axillary nodes
Lymph nodes in the armpit
B Cell
Lymphocyte that matures into a plasma cell to secrete antibodies
Cell-mediated immunity
T cells that respond to antigens and destroy them
Cervical Nodes
lymph nodes in the neck region
complement system
proteins in the blood that help antibodies kill their target
cytokines
proteins secreted by cytotoxic T cells to aid in antigen destruction
cytotoxic T cell
lymphocyte that directly kills antigens
dendritic cell
antigen-presenting cell
helper T cell (CD4-positive T cell)
lymphocyte that aids B cells and stimulates T cells
humoral immunity
B cells produce antibodies after exposure to specific antigens; a type of adaptive immunity
immunity
body’s ability to resist toxins, infection, foreign organisms that damage tissues and organs
immunoglobulins
antibodies such as IgA, IgE, IgG, IgM, and IgD secreted by plasma cells in response to the presence of an antigen
immunotherapy
use of immune cells, antibodies, or vaccines to treat or prevent disease
inguinal nodes
Nodes in the groin region
interferons
proteins secreted by T cells to aid and regulate immune response
interleukins
proteins that stimulate the growth of B & T lymphocytes
Interstitial fluid
fluid in the spaces between cells
lymph
thin, watery fluid found within lymphatic vessels and collected from tissues throughout the body
lymph capillaries
tiniest lymphatic vessels
lymphoid organs
lymph nodes, spleen, thymus gland
lymph node
collection of stationary solid lymphatic tissue along lymph vessels
lymph vessel
carrier of lymph throughout the body
macrophage
large phagocyte found in lymph nodes and other tissues of the body
mediastinal nodes
lymph nodes in the area between the lungs in the thoracic cavity
mesentric nodes
lymph nodes in the mesentery
monoclonal antibody
antibody produced in a laboratory to attack antigens and destroy cells
natural immunity
protection that an individual is born with to fight infection such as neutrophils, monocytes, macrophages, etc.
paraaortic nodes
lymph nodes near the aorta in the lumbar area of the body
plasma cell
lymphocyte that secretes antibodies
right lymphatic duct
lymphatic vessel in the chest that drains lymph from the upper right part of the body
spleen
organ in the LUQ of the abdomen that destroys worn out red blood cells
suppressor T cell
lymphocte that inhibits the activity of B & T cells
T cell
lymphocyte that acts directly on antigens to destroy them or produce chemical that are toxic to antigens
tolerance
ability of T lymphocytes to recognize and accept the body’s own antigens as “self” or friendly so the body doesn’t react against the body
thoracic duct
large lymphatic vessel that drains lymph from the lower and left side of the body
thymus gland
lymphoid organ in the mediastinum that conditions T cells to react to foreign cells and aids in the immune respnse
tonsils
masses of lymphatic tissue in the back of the oropharynx
toxin
poison
vaccination
exposure of an individual to a foreign proteins that provokes an immune response
vaccine
weakened or killed microorganisms, toxins, or other proteins given to induce immunity to infection or disease
