Flashcards in Chapter 13: Need to Know Deck (45):
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

bilirubin

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

5

differentiation

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

6

heparin

anticoagulant found in blood and tissue cells

7

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removal of plasma from withdrawn blood by centrifuge.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 Fresh-frozen plasma or salt solution is used to replace withdrawn plasma.

8

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

9

anemia

deficiency in erythrocytes or hemoglobin

10

aplastic anemia

failure of blood cell production in the bone marrow

11

hemolytic anemia

reduction in red cells due to excessive destruction

12

pernicious anemia

lack of mature erythrocytes caused by inability to absorb vitamin B12 into the bloodstream

13

sickle cell anemia

hereditary disorder or abnormal hemoglobin producing sickle-shaped erythrocytes and hemolysis

14

pancytopenia

abnormal deficiency in all blood cells

15

thalassemia

inherited defect in ability to produce hemoglobin, leading to hypochromia

16

hemophilia

excessive bleeding caused by hereditary lack of blood clotting factors (factor VIII or IX) necessary for blood clotting

17

leukemia

increase in cancerous white blood cells (leukocytes)

18

AML

acute myelogenous (myelocytic) leukemia

19

ALL

acute lymphocytic leukemia

20

CML

chronic myelogenous (myelocytic) leukemia

21

CLL

chronic lymphocytic leukemia

22

mononucleosis

infectious disease marked by increased numbers of mononuclear leukocytes and enlarges cervical lymph nodes

23

EBV

Epstein-Barr virus; cause of mononucleosis

24

coagulation time

time required for venous blood to clot in a test tube (normal time is less than 15minutes)

25

CBC

complete blood count

26

complete blood count

determination of numbers of blood cells, hemoglobin concentration, hematocrit and red cell values--MCH, MCV, MCHC

27

ESR

erythrocyte sedimentation rate

28

erythrocyte sedimentation rate

speed at which erythrocytes settle out of plasma

29

Hct

hematocrit

30

hematocrit

percentage of erythrocytes in a volume of blood

31

H, Hg, Hgb, HGB

hemoglobin test

32

hemoglobin test

total amount of hemoglobin in a sample of peripheral blood

33

red blood cell count

number of erythrocytes per cubic millimeter or microlitre of blood

34

white blood cell count

number of leukocytes per cubin millimeter or microliter of blood

35

apheresis

separation of blood into component parts and removal of a select portion from the blood

36

BMT

bone marrow transplantation

37

EPO

erythropoietin

38

ESR

erythrocyte sedimentation rate

39

sed rate

erythrocyte sedimentation rate

40

lymphs

lymphocytes

41

mono

monocyte

42

PT
pro time

prothrombin time

43

PTT

partial thromboplastin time

44

RBC

red blood cell; red blood cell count

45

WBC

white blood cell; white blood cell count
