agranulocytes

white blood cells lacking granules in their cytoplasm lymphocytes and monocytes

abumin

plasma protein that maintains blood volume

anemia

decrease in RBC or hemoglobin

antibody

proteins produced by white blood cells in response to antigens

antigens

foreign substance that stimulates the production of andibodies

basophils

granulocytic WBC seen in anaphylaxis

bilirubin

metabolite of hemoglobin breakdown, conjugated in the liver

coagulation

blood clotting

eosinophil

ganulocytic WBC seen with allergies and parasites

erythrocyte

RBC

erythropoietin

hormone secreted by the kidneys to stimulate RBC production

fibrin

protein threads that form the basis of a clot

fibrinogen

plasma protein that is converted to fibrin in the clotting process

globulins

plasma proteins such as alpha beta and gamma, antibodies

heme

iron containing portion of hemoglobin

granulocytes

WBC containing granules in their cytoplasm, neurophils, eosinophils and basophils

hemoglobin

oxygen carrying pigment of RBC

leukocyte

WBC

lymphocyte

agranulocyte that produces antibodies

macrophage

monocyte that migrate from the blood to tissue

megakaryocyte

precursor to a platelet formed in the bone marrow

meutrophil

granulocytic WBC thatis the bodys primary bacterial phagocyte

plasma

fluid portion of anticoagulated or circulating blood

prothrombin

plasma potein that is converted to thrombin in the clotting process

reticulocyte

immature RBC

serum

fluid portion of coagulated blood

thrombin

an enzyme that results from the activation of prothrombin

thrombocyte

platelet clotting cell

anticoagulant

agent that prevents coagulation of blood

bleeding time

coagulation test used to measure the time required for a small wound to stop bleeding

bone marrow biopsy

procedure to obtain a bone marrow sample for cytology

complete blood count

blood panel that includes WBC, RBC, and platelet count

disseminated intravascular coagulation

formation of clots throughout microcirculation which leads to hemorrhage due to consumption of clotting factors

dyscrasia

any abnormal or pathological condition of blood

hematocrit

percentage of red blood cells in a volume of blood, packed cell volume PCV

hemophilia

bleeding disorder in which the animal is lacking one or more clotting proteins

hemorrhage

escape of blood through ruptured blood vessels

icterus

yellowish coloration of the plasma caused by increased bilirubin

leukemia

increase in the number of cancerous WBC

lipemia

flat in the blood, white plasma color

phlebotomy

venipuncture the act of drawing blood

transfusion

transfer of blood and blood components from one animal to another

von villebrands disease

congenital bleeding disorder in which the animal is lacking VW clotting factors, pinscher, collie, sheepdog, irish wolfhound

coumarin coumpund found in rodents, once ingested it binds to Vitamin K in the body

white blood cell differential

test to cont the different types of WBC on a slide
