19
Q

heparin

A

anticoagulant found in blood and tissue cells

20
Q

immune reaction

A

response of the immune system to foreign invasion

21
Q

immunoglobulin

A

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

22
Q

leukocyte

A

white blood cell

23
Q

lymphocyte

A

mononuclear leukocyte that produces antibodies

24
Q

macrophage

A

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removal of plasma from withdrawn blood by centrifuge.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 Fresh-frozen plasma or salt solution is used to replace withdrawn plasma.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