Flashcards in Chap 13, Blood System, Terminology Deck (49)
1

basophil

White blood cell (leukocyte) containing dark granules that stain with a basic dye. The suffix -phil means attraction to.

2

hypochromic

Pert. to a deficiency in colour; decrease in hemoglobin in red blood cells. Hypochromic anemia is marked by a decreased concentration of hemoglobin in red blood cells.

3

anticoagulant

Substance that prevents blood clotting.

4

coagulopathy

Disease of blood clotting.

5

cytology

Study of cells.

6

eosinophil

A granular white blood cell with cytoplasmic granules that stain with eosin (a reddish dye).

7

erythroblast

Immature, developing red blood cell. (-blast means immature).

8

granulocyte

White blood cell with numerous dark-staining granules;eosinophil, neutrophil, and basophil.

9

hemolysis

Destruction of red blood cells. Destruction or breakdown of red blood cells. See hemolytic anemia.

10

hematocrit

Percentage of red blood cells in a given volume of blood. The suffix -crit means to separate. The hematocrit gives the percentage of RBCs in a volume of blood.

11

hemoglobinopathy

Disease or defect of hemoglobin production. Sickle cell anemia is an example.

12

anisocytosis

Inequality in the size of red blood cells. An abnormality of red blood cells; they are of unequal (anis/o) size; -cytosis means an increase in the number of cells.

13

magakaryocyte

Large, giant cell with a big nucleus; platelet precursor found in the bone marrow.

14

leukopenia

Deficiency of white blood cells.

15

monocyte

White blood cell with one large nucleus; capable of killing foreign substances by phagocytosis (ingestion). The cell has a single, rather than a multilobed, nucleus.

16

morphology

Study of the shape or form of cells.

17

myeloblast

Immature granulocytic white blood cell; a cell normally only found in the bone marrow. The suffix -blast indicates an immature cell.

18

myelodysplasia

Abnormal (ineffective) production of myeloid cells in bone marrow. (-plasia means development, formation, growth; increased # of cell growth). This is a preleukemic condition.

19

neutropenia

Deficiency in neutrophils. This term refers to neutrophils.

20

polymorphonuclear

Pert. to a multilobed nucleus (in granulocytic white blood cells).

21

phagocyte

Cells that engulf another cell or foreign organism and destroys it.

22

poikilocytosis

Variation in the shape of red blood cells. Irregularity in the shape of red blood cells. Poikilocytosis occurs in certain types of anemia.

23

sideropenia

Deficiency of iron in the blood.

24

spherocytosis

Increase in numbers of sphere-shaped RBCs, as in a type of anemia (hemolytic anemia). In this condition, the erythrocyte has a round shape, making the cell fragile and easity able to be destroyed.

25

thrombocytopenia

Deficiency of clotting cells.

26

plasmapheresis

Removal of plasma from withdrawn blood by centrifuge. A centrifuge spins blood to remove plasma from the other parts of blood.

27

leukapheresis

Mechanical separation of white blood cells from the rest of the blood.

28

plateletpheresis

Separation of platelets from the rest of the blood. Note that the a of apheresis is dropped in this term. Platelets are removed from the donor's blood (and used in a patient), and the remainder of the blood is reinfused into the donor.

29

monoblast

Immature monocyte.

30

macrocytosis

Abnormal condition (slight increase in #'s) of macrocytes. Presence of large red blood cells in the blood. Macrocytes are erythrocytes that are larger (macro-) than normal.

31

microcytosis

Abnormal condition. Increased numbers of smaller than normal red blood cells. These are erythrocytes that are smaller (micro-) than normal.

32

leukemia

Disease of high numbers of malignant (cancerous) white blood cells.

33

fibrinogen

Plasma protein that is converted to fibrin in the clotting process. Fibrin is a protein that forms the basis of a blood clot.

34

hemoglobin

Blood protein containing iron; carries oxygen in red blood cells.

35

immunoglobulins

Antibodies (proteins) secreted by B-cell lymphocytes (plasma cells). Protein (antibody produced by plasma cells) that acts to protect the body by destroying antigens.

36

thrombolytic therapy

Treatment with drugs to break down clots that may abnormally form in blood vessels. Used to dissolve clots.

37

myeloid

Derived from bone marrow.

38

thrombosis

Abnormal condition of clot formation in a blood vessel. Abnormal condition of clotting.

39

granulocytopenia

Deficiency of granulocytes (white blood cells).

40

pancytopenia

Deficiency of all blood cells.

41

macrophage

Large phagocytic cell (in blood and tissues) that eats (engulfs) other cells. A large phagocyte that destroys worn-out red blood cells and foreign material. It is derived from a monocyte.

42

eosinophilia

Increase in numbers of eosinophils in the bloodstream.

43

neutrophilia

Increased numbers of neutrophils.

44

electrophoresis

Technique used to separate serum proteins by electrical charge. Separation of proteins in a solution by using an electric current (used to separate protein fractions of serum, urine, or cerebrospinal fluid).

45

hematopoiesis

Formation of blood cells.

46

erythropoiesis

Formation of erythrocytes (red blood cells). Erythropoietin is produced by the kidneys to stimulate erythrocyte formation.

47

myelopoiesis

Formation of bone marrow.

48

hemostasis

Stoppage of bleeding or circulation of blood or stoppage of the flow of blood.

49

neutrophil

A granular leukocyte; important disease-fighting cell.
