Flashcards in Blood System Deck (80):
1

albumin

protein in blood; maintains amount of water in the blood

2

antibody (Ab)

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

3

antigen

foreign substance that stimulates the production of an antibody

4

basophil

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

5

bilirubin

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

6

coagulation

blood clotting

7

colony-stimulating factor

protein that stimulates growth of WBC's (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 cells containing granules that stain red; associated with allergic reactions

11

erythroblast

immature red blood cells

12

erythrocyte

mature red blood cell. There are about 5 million per microliter of blood

13

erythropoietin (EPO)

Hormone secreted by the kidneys; stimulates red blood cell formation

14

fibrin

protein that forms the basis of a blood clot

15

fibrinogen

plasma protein that is converted to fibrin in the clotting process

16

globulin

plasma protein; alpha, beta and gamma

17

granulocyte

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

18

hematopoietic stem cell

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

19

hemoglobin

blood protein containing iron; carries oxygen in red blood cells

20

hemolysis

destruction or breakdown of blood cells

21

heparin

anticoagulant found in blood and tissue cells

22

immune reaction

response of the immune system to foreign invasion

23

immunoglobulin

protein with antibody activity; examples include IgG, IgM, IgA, IgE, IgD.

24

leukocyte

WBC

25

lymphocyte

mononuclear leukocyte that produces antibodies

26

macrophages

monocyte that migrates from blood into tissue spaces. As a phagocyte, it engulfs foreign materials.

27

Megakaryocyte

large platelet precursor cell found in the bone marrow

28

monocyte

leukocyte with one large nucleus

29

mononuclear

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

30

myeloblast

immature bone marrow that gives rise to granulocytes

31

neutrophil

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

32

plasma

liquid portion of blood. Contains water, sugar, salts, proteins, lipids, hormones and vitamins

33

plasmapheresis

removal of plasma from withdrawn blood by centrifuge.

34

platelet

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

35

polymorphonuclear

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

36

prothrombin

Plasma protein; converted to thrombin in the clotting process

37

reticulocyte

immature erythrocyte.

38

Rh factor

antigen on RBCs of Rh-positive individuals.

39

serum

Plasma minus clotting proteins and cells. Clear, yellowish fluid that separates from blood when it is allowed to clot.

40

stem cell.

Unspecialized cell that gives rise to mature, specialized cells.

41

thrombin

emzyme that converts fibrinogen to fibrin during coagulation.

42

thrombocyte

platelet.
