Flashcards in Chapter 13: Vocabulary Deck (40):
1

albumin

protein in blood; maintains the proper amount of water in the blood

2

antibody (Ab)

specific protein (immunoglobulin) produced by lymphocytes in response to bacteria, viruses or other antigens. An antibody is specific to an antigen and inactivates it

3

antigen

substance (usually foreign) that stimulates the production of an antibody

4

basophil

white blood cell containing granules that stain blue; associated with release of histamine and heparin

5

bilirubin

orange-yellow pigment in bile; formed by the breakdown of hemoglobin when red blood cells are destroyed

6

coagulation

blood clotting

7

colony-stimulating factor (CSF)

protein that stimulates growth of white blood cells (granulocytes)

8

differentiation

change in structure and function of a cell as it matures; specialization

9

electrophoresis

method of separating serum proteins by electrical charge

10

eosinophil

white blood cell containing granules that stain red; associated with allergic reactions

11

erythroblast

immature red blood cell

12

erythroprotein (EPO)

hormone secreted by the kidneys; stimulates red blood cell formation

13

fibrin

protein that forms the basis of a blood clot

14

fibrinogen

plasma protein that is converted to fibrin in the clotting process

15

globulin

plasma protein; alpha, beta, and gamma (immune) globulins are examples

16

granulocyte

white blood cell with numerous dark staining granules: eosinophil, neutrophil, and basophil

17

hematopoietic stem cell

cell int he bone marrow that gives rise to all types of blood cells

18

hemolysis

destruction of breakdown of blood (red blood cells)

19

heparin

anticoagulant found in blood and tissue cells

20

immune reaction

response of the immune system to foreign invasion

21

immunoglobulin

protein (globulin) with antibody activity; examples are IgG, IgM, IgA, IgE, IgD

22

leukocyte

white blood cell

23

lymphocyte

mononuclear leukocyte that produces antibodies

24

macrophage

monocyte that migrates from the blood to tissue spaces. As a phagocyte, it engulfs foreign material and debris. In the liver, spleen, and bone marrow, macrophages destroy worn out red blood cells

25

megakaryocyte

large platelet precursor cell found in the bone marrow

26

monocyte

leukocyte with one large nucleus. It is a cell that engulfs foreign material and debris. Monocytes become macrophages as they leave the blood and enter body tissues

27

mononuclear

pertaining to a cell (leukocyte) with a single round nucleus; lymphocytes and monocytes are mononuclear leukocytes

28

myeloblast

immature bone marrow that gives rise to granulocytes

29

neutrophil

granulocytic leukocyte formed in bone marrow. It is phagocytic tissue-fighting cell. Also called a polymorphonuclear leukocyte

30

plasma

liquid portion of blood; contains water, proteins, salts, nutrients, lipids, hormones and vitamins

31

plasmapheresis

removal of plasma from withdrawn blood by centrifuge. Collected cells are retransfused back into the donor. Fresh-frozen plasma or salt solution is used to replace withdrawn plasma.

32

platelet

small blood fragment that collects at sites of injury to begin the clotting process

33

polymorphonuclear

pertaining to a white blood cell with a multi-lobed; neutrophil

34

prothrombin

plasma protein; converted to thrombin in the clotting process

35

reticulocyte

immature erythrocyte. a network of strands (reticulin) is seen after staining the cell with special dyes

36

rH factor

antigen on red blood cells of Eh-positive (Rh+) individuals

37

serum

plasma minus clotting proteins and cells. Clear, yellowish fluid that separates from blood when it is allowed to clot. It is formed from plasma, but does not contain protein-coagulation factors

38

stem cell

unspecialized cell that gives rise to mature, specialized forms. A hematopoietic stem cell is the progenitor for all different types of blood cells

39

thrombin

enzyme that converts fibrinogen to fibrin during coagulation

40

thrombocyte

platelet
