Lymph Flashcards
Adaptive immunity
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
Lymphocytes that matures into a pasta cells to secrete antibodies
Cell mediated immunity
T cells that responds to antigens and destroys them
Cervical nodes
Lymph nodes in neck region
Complement system
Protein in the blood that help antibodies and kills their target
Cytokines
Proteins secreted by cytotoxic T cells to aid in antigen destruction
Cytotoxic T cell
CD8+ T cell
Lymphocytes that directly kills antigens
Dendritic cells
Antigen-presenting cell; shows T and B cells what to attack
Helper T cells
CD4+ T cells
Lymphocytes 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 tissue and organs
Immunoglobulins
Antibodies secreted by plasma cells in response to the presence of an antigen
Immunotherapy
Use of immune cells, antibodies, or vaccine to treat or prevent disease
Inguinal nodes
Lymph nodes in the groin region
Interferon
Proteins secreted by T cells and other cells to aid and regulate the immune response
Interleukins
Proteins that stimulate the growth of B and T lymphocyte
Interstatitial fluid
Fluid in the space betweencells; becomes lymph in lymph capillaries
Lymph
Thin, water fluid within lymphatic vessels and collected from tissues throughout the body
Lymph capillaries
Tiniest lymphatic vessels
Lymphoid organ
Lymph nodes, spleen, and thymus gland
Lymph node
Collection of stationary solid lymphatic tissue along lymph vessels
Lymph vessels
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 inin the thoracic cavity
Mesenteric nodes
Lymph nodes is mesentery
Monoclonal antibody
An antibody produced in a laboratory to attack antigens and to destroy cells
Natural immunity
Protection that an individual is born with to fight infection
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
Vessel in the chest that drains lymph from the upper right part; empties into large neck vein
Spleen
Organ in left upper quadrant of the abdomen that destroys worn out RBC’s, activates lymphocytes, and stores blood
Suppressor T call (Treg)
Lymphocyte that inhibits the activity of B and T cells
T cells (T lymphocyte)
Lymphocytes that acts directly on antigens to destroy them or produces chemicals toxic to antigens
Tolerance
Ability of T lymphocyte to recognize and accept the body’s own antigens as “self” or friendly
Thoracic duct
Drains lymph from the lower and left side of body; empties into large veins in neck
Thymus gland
Lymphoid organ in the mediastinum that condition T cells to react to foreign cells
Tonsils
Masses of lymphatic tissue in back of the oropharynx
Toxin
Poision
Vaccinations
Exposure of an individual to an antigen that provokes an immune response that will destroy any cells with the antigenand will protect against infection
Reverse transcripts inhhibitors
Inhibits viral enzyme called reverse anti transcriptase
Protease inhibitor
Inhibits viral proteolytic enzyme
HARRT
RTI and protease inhibitors therapy
