M3C Lymphatic Vocab Flashcards
adaptive immunity
the ability to recognize and remember specific antigens and mount an attack on them
adenoids
mass of lymphatic tissue in the nasopharynx
antibody
protein produced by B cells to destroy antigens
antigen
substance that the body recognizes as foreign
evokes an immune response
axillary nodes
lymph nodes in the armpit
B cell (B lymphocyte)
lymphocyte that matures into a plasma cell to secrete antibodies
cell-mediated immunity
T cells respond to antigens and destroy them
a type of adaptive immunity
cervical nodes
lymph nodes in the neck region
complement system
set of 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 (CD8+ T cell)
lymphocyte that directly kills antigens
dendritic cell
antigen-presenting cell
shows T and B cells what to attack
helper T cell (CD4+ T cell)
lymphocyte that aids B cells and stimulates T cells
humoral immunity
B cells produce antibodies after exposure to specific antigens
type of adaptive immunity
immunity
body’s ability to resist foreign organisms and toxins that damage tissues and organs
includes natural and adaptive immunity
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 disease
inguinal nodes
lymph nodes in the groin region
interferons
proteins (cytokines) secreted by T cells and other cells to aid and regulate the immune response
interleukins
proteins (cytokines) that stimulate the growth of B and T lymphocytes
interstitial fluid
fluid in the space between cells
this fluid becomes lymph when it enters lymph capillaries
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, and thymus glands
lymph node
collection of stationary solid lymphatic tissue along lymph vessels
contains cells (lymphocytes and macrophages) that fight infection
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 chest cavity
mesenteric nodes
lymph nodes in the mesentery
monoclonal antibody
antibody produced in a laboratory to attack antigens and to destroy cells
natural immunity
protection that an individual is born with to fight infection such as neutrophils, monocytes, macrophages, and NK cells
paraaortic nodes
lymph nodes near the aorta in the lumbar area of the body
plasma cell
lymphocyte that secretes antibodies
matures from B lymphocytes
right lymphatic duct
lymphatic vessel in the chest that drains lymph from the upper right part of the body
spleen
organ in the left upper quadrant of the abdomen that destroys worn-out red blood cells, activates lymphocytes, and stores blood
suppressor T cell (Treg, regulatory T cell)
lymphocyte that inhibits the activity of B and T cells
T cell (T lymphocyte)
lymphocyte that acts directly on antigens to destroy them or produce chemicals that are toxic to antigens
tolerance
ability of T lymphocytes to recognize and accept the body’s own antigens as “self” or friendly
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 response
tonsils
masses of lymphatic tissue in the back of the oropharynx
vaccination
exposure of an individual to a foreign protein that provokes an immune response
vaccine
weakened or dead antigen is given to induce production of antibodies
