60 Cards in this Set

  • Front
  • Back
  • 3rd side (hint)
antibody
protective protein produced by B lymphocytes in response to presence of a foreign substance called an antigen
antigen
substance recognized as harmful to the host and stimulates formation of antibodies in an immunocompetent individual
bile pigments
substances derived from the breakdown of hemoglobin, produced by the liver, and excreted in the born of bile
cytokines
chemical substances produced by certain cells that initiate, inhibit, increase, or decrease the activity of other cells
cytokines are important chemical communicators in the immune response, regulating many activities associated with immunity and inflammation
extracellular fluid
all body fluids found outside cells, including interstitial fluid, plasma, lymph, and CSF
provides stable environment for body cells
host
organism that maintains and harbors another organism
immunocompetent
ability to develop an immune response, or the ability to recognize antigens and respond to them
natural killer cells
specialized lymphocytes that kill abnormal cells by releasing chemicals that destroy the cell membrane causing its intracellular fluids to leak out
NK cells destroy virally infected cells and tumor cells
aden/o
gland
agglutin/o
clumping, gluing
bas/o
base, alkaline
blast/o
embryonic cell
eosin/o
dawn (rose-colored)
granul/o
granule
hem/o

hemat/o
blood
immun/o
immune, immunity, safe
lymphaden/o
lymph gland
lymph/o
lymph
lymphangi/o
lymph vessel
myel/o
bine marrow, spinal cord
neutr/o
neutral, neither
phag/o
swallowing, eating
plas/o
formation, growth
poikil/o
vaired, irregular

poikilocyte- cell that is irregular or varies in shape
reticul/o
net, mesh
ser/o
serum
sider/o
iron

sideropenia - deficiency of iron
splen/o
spleen
thromb/o
blood clot
thym/o
thymus gland
-blast
embryonic cell
-emia
blood condition
-globin
protein
-graft
transplantation
-osis
abnormal condition, increase (used primarily with blood cells)
-penia
decrease, deficiency
-phil
attraction for
-phoresis
carrying, transmission
-phylaxis
protection
-poiesis
formation, production
-stasis
standing still
allo-
other, differing from the normal
aniso-
unequal, dissimilar
iso-
same, equal
anisocytosis
condition of marked variation in the size of erythrocytes when observed on blood smear
ascites
accumulation of serous fluid in the peritoneal or pleural cavity
bacteremia
presence of viable bacteria circulating in the bloodstream usually transient in nature
graft rejection
destruction of transplanted organ or tissue by recipients immune system
graft-versus-host disease (GVHD)
condition that occurs following bone marrow transplant in which the immune cells in the transplanted bone marrow produce antibodies against the host's tissues
GVHD can be acute or chronic. the cute form appears within 2 months of the transplant, the chronic form usually appears within 3 months. GVHD may also occur as a reaction to a blood transfusion
hematoma
localized accumulation of blood, usually closeted, in an organ, space or tissue due to a break in or severing of a blood vessel
hemoglobinopathy
any disorder caused by abnormalities in the hemoglobin molecule
hemolysis
destruction of RBCs with a release of hemoglobin that diffuses into the surrounding fluid
immunity
state of being protected against infectious disease
active immunity
immunity produced by the person's own immune system
passive immunity
immunity in which antibodies or other immune substances formed in one individual are transferred to another individual to provide immediate temporary immunity
lymphadenopathy
any disease of the lymph nodes
lymphosarcoma
malignant neoplastic disorder of lymphatic tissue (not related to hodgkin disease)
septicemia
serious, life-threatening bloodstream infection that may arise from other infections throughout the body, such as pneumonia, UTIs, meningitis, or infections of the bone or GI tract, also called blood infection or blood poisoning
serology
lab test to detect the presence of antibodies, antigens, or immune substances
titer
blood test that measures the amount of antibodies in blood, commonly used as indicator for immune status
