| Spelling | Terminology |
|---|---|
| Blood | Liquid tissue containing plasma & formed elements |
| Erythrocytes | Red Blood Cells |
| Leukocytes | White Blood Cells |
| Thrombocytes | Platelets; cells which initiate clotting process |
| Neutrophils | WBC responsible for phagocytosis; increases during short tem/acute infections |
| Basophils | WBC which releases histamine; increases during allergic reaction |
| Eosinophils | WBC which counteracts histamine |
| Monocytes | (Aka Macrophage) WBC responsible for phagocytosis; increased during long-term or chronic infections |
| Lymphocytes | WBC responsible for maintaining the immune system; includes T-cells and B-cells |
| Antigen | any foreign substance that is harmful to the body |
| Antibody | defense mechanism; immune response to an antigen |
| Plasma | Liquid portion of whole blood; contains clotting factors- found ina tube that contains an anticoagulant |
| Serum | liquid portion of clotted blood that doesn't have clotting factors; found in a tube that does not contain an anticoagulant (Ex: SST/Red) |
| Erythrocytolysis | Destruction of red blood cells |
| Hemostasis | to stop bleeding |
| Megakaryocyte | cell in bone marrow which produces thrombocytes |
| Leukocytosis | increase in WBC's; increases during bacterial infections |
| Leukopenia | decrease in WBC's; increases during viral infections or in pts. w/ bone marrow depressions such as cancer patients on chemotherapy |
| Morphology | the study of the shape of cells |
| Phagocyte | a cell capable of ingesting foreign substances and other cells |
| Phagocytosis | "cellular eating" |
| Macrophage | (Aka Monocyte) WBC capable of phagocytosis |
| Poikilocytosis | RBC that vary in cell shape |
| Anisocytosis | RBC that vary in cell size |
| Hyperchromasia | RBC that have an increased red color |
| Hypochromasia | RBC that have a decreased red color |
| Normochromasia | RBC that have a normal red color |
| Polychromasia | RBC that vary in red color |
| Reticulocyte | immature, nucleated RBC |
| Thrombus | blood clot |
| Thrombolysis | destruction of a blood clot |
| Thrombocytopenia | decreased amount of platelets |
| Hemoglobin | iron containng pigment of RBC; helps transport oxygen |
| Hemopoiesis | formation of a blood clot |
| Anticoagulant | medication or chemical that inhibits blood from clotting |
| Dyscrasia | any blood abnormality |
| Hematoma | localized collection of blood under the skin |
| Serology | the study of Serum (Serology blood tests are drawn in an SST/RED top tube) |
| Transfusion | receiving blood to replenish blood lost |
| Cross-Match | blood test to determine whether donated blood will be compatible with recipient's blood (RED TOP TUBE ONLY) |
| Bleeding Time | test to determine the amount of time it takes for a small incision to stop bleeding |
| Complete Blood Count | (CBC) Test to determine the cellular components of blood |
| Reb Blood Cell Count | Test to determine the approximate number of RBC's in a cubic millimeter (CU/MM) of blood |
| Hematocrit | test to determine the percentage of RBC's in a volume of blood |
| Differential | test to determine the percentage of the five types of WBC's- Neutrophils, Lymphocytes, Monocytes, Eosinophils & Basophils) |
| Erythrocyte Sedimentation Rate | (ESR) Test that measures the speed at which RBC's settle in a tube of anticoagulated blood |
| Prothrombin Time | Pt. test to determine the amount of time it takes for a clot to form |
| Hemostatics | medications or chemicals used to stop bleeding |
| Phenylketonuria Test | (PKU) test done on newborns at birth and at 4-6 weeks of age; if positive and untreated- may lead to mental retardation |
| Hemophilia | hereditary disease where there is a lack of factor VIII and the blood doesn't clot properly |
| Lancet | small, sharp instrument used to perform capillary punctures |
| Capillary Puncture | puncture of a capillary to withdraw blood (FINGER, HEEL, BIG TOE, EAR LOBE OR INNER ARM) |
| Venipuncture | Surgical puncture of a vein to withdraw blood |
| Phlebotomy | incision into a vein to withdraw blood |
| Tourniquet | strap used to occlude the veins when performing venipuncture |
| Glucolysis | destruction of glucose |
| Glucometer | instrument used to measure the amount of glucose in blood |
| Biohazardous Waste | waste that is considered to be contaminated and potentially infectious |
| Hepatitis B | viral infection and inflammation of the liver causing jaundice |
| Antecubital Fossa | the inside of the elbow |
| Albumin | the most abundant protein in the blood |
| Arteriole | small artery |
| Artery | vessel which carries blood away from the heart |
| Basilic Vein | large vein of the inner side of the upper arm (PINKY SIDE) |
| Cephalic Vein | Large vein on the outer side of the upper arm (THUMB SIDE) |
| Accessory Cephalic Vein | vein on outer side of arm which empties into the cephalic vein |
| Median Cubital Vein | large vein in the middle of the upper arm (ANTECUBITAL FOSSA) Vein that is most commonly used for venipuncture |
| Buffy Coat | thin layer between plasma and RBC in a volume of anticoagulated blood; contains WBC's and Platelets |
| Ecchymosis | bruising |
| Petechiae | pin-sized red dots on the skin caused by broken capillaries |
| Hemapheresis | process where blood is withdrawn from a patient |
