area in the middle of the arm, in front of the elbow, that houses the veins most commonly used for venipuncture

3
Q

antibody

A

complex protein substance produced in the presence of foreign substances, such as bacteria, viruses, lipids, or carbs, in order to protect the body

4
Q

Anticoagulant

A

agent that prevents blood from clotting

5
Q

antigen

A

substance that causes the formation of an antibody when introduced into blood or tissue

6
Q

aorta

A

largest artery in the body

7
Q

arteriole

A

smaller branch of an artery; a mini artery

8
Q

artery

A

blood vessel that carries blood from the heart to the tissues

9
Q

atrium (atria)

A

one of two top chambers of the heart, known as the holding chambers

10
Q

basilic vein

A

vein, used for venipuncture, that is not well anchored & tends to roll

11
Q

basophil

A

least numerous type of leukocytes; the granules are large & stain dark blue from basic dyes & often obscure the nucleus

12
Q

b-cell lymphocyte

A

type of lymphocyte that produces antibodies upon stimulation

13
Q

blood type

A

description, based on the ABO classification system, of the presence of specific antigens on the surface of RBC’s

14
Q

capillary

A

smallest of all blood vessels, which allow the exchange of micronutrients & oxygen between the cells & the blood; capillaries connect arteries to veins

15
Q

centrifugation

A

process of separating components of a specimen using a centrifuge

16
Q

cephalic vein

A

vein, used for venipuncture, that may be difficult to palpate

17
Q

coagulation

A

cessation of bleeding; clot formation

18
Q

cytoplasm

A

area of the cell outside of the nucleus

19
Q

deoxygenated

A

presence of a larger quantity of carbon dioxide than oxygen

20
Q

diapedesis

A

process by which certain WBC’s can exit the capillaries & enter the tissues in response to pathogens

21
Q

eosinophil

A

leukocyte whose granules stain bright orange-red from eosin; aids the body in fighting parasites & numbers increase in allergies

22
Q

erythrocyte

A

red blood cell; an anuclear, biconcave disk-shaped blood cell that is responsible for transporting oxygen

23
Q

fibrin

A

filamentous protein formed by the action of thrombin on fibrinogen

24
Q

fibrinogen

A

protein found in plasma; essential for clotting

25
Q

granulocyte

A

white blood cells containing granules of various colors & chemical makeup; basophils, eosinophils, & neutrophils

26
Q

hematoma

A

collection of blood under the skin due to leakage of blood from a punctured vein or artery

27
Q

hematopoietic

A

blood-forming tissues

28
Q

hemoglobin

A

iron-rich protein molecules found in RBC’s; transports oxygen & carbon dioxide

29
Q

hemolysis

A

destruction of RBC’s that allows hemoglobin to be released from the RBC’s

30
Q

hemostasis

A

coagulation, or clot formation, that repairs vessel damage & stops blood loss

31
Q

jaundice

A

yellow coloration to skin, eyes & mucous membranes

32
Q

leukocyte

A

WBC; round cell with a nucleus whose main function is to combat infection & remove disintegrating tissues

33
Q

lymphocyte

A

leukocyte produced in the lymphoid tissue; a nongranular leukocyte that has a role in the body’s immune system

34
Q

lymphoid

A

pertaining to the lymphatic system or resembling lymphocytes

35
Q

median cubital vein

A

most commonly used vein for venipuncture; located in the middle of the forearm

36
Q

monocyte

A

large leukocyte formed in bone marrow, with abundant cytoplasm & a kidney-shaped nucleus; ingests bacteria, dying cells, & debris in tissues

37
Q

myeloid

A

developed from bone marrow

38
Q

Natural Killer cells

A

type of lymphocytes that can attack & destroy tumor cells or cells that have been infected by viruses

39
Q

neutrophil

A

leukocyte that engulfs & digests pathogens found in tissues; its granules stain lavendar

40
Q

oxygenated

A

containing a higher concentration of oxygen that carbon dioxide

41
Q

A

process by which bacteria & antigens are surrounded & engulfed by leukocytes

42
