Unit 2 - Chapter 13 - Blood Systems Flashcards
what is the function of blood
transports foods, gases and wastes to and from the cells of the body
what are other items that blood transports
- chemical messengers
- blood proteins
- white blood cells
- platelets
what is in the composition of blood
- cells (erythocytes, leukocytes, platelets)
- plasma
- water
- proteins
- sugar
- salts
- hormones
- lipids
- vitamins
what percentage of blood do cell make up
45%
what are erythrocytes
red blood cells transport nutrients and oxygen
what are thrombocytes
platelets that clot blood
what are leukocytes
white blood cells
how many types of white blood cells (leukocytes) are there and what are their names
5
basophils
eosinophils
neutrophils
monocytes
lymphocytes
what are basophils
- White blood cell that contains granules
that stain blue - cells that prevent clotting (contain heparin) and aid in allergic responses (contain histamine)
what are eosinophils
- White blood cell that contains
granules that stain red - phagocytic cells involved in allergic responses and parasitic infections
what are neutrophils
- granulocytic leukocyte formed in bone marrow
- phagocytic cells that accumulate at sites of infection
what are monocytes
- leukocyte with one large nucleus
- phagocytic cells that become macrophages and digest bacteria and tissue debris
what are lymphocytes
control the immune response, make antibodies to antigens
what are the different types of plasma proteins
- albumin
- gloubins (immunogloubins)
- fibrinogen
- prothrombin
what does type a blood consist of
a antigen and anti-b antibody
what does type b blood consist of
b antigen and anti-a antibody
what does type ab blood consist of
a and b antigens and no antibodies (universal recipient)
what does type o blood consist of
no a or b antigens and both anti-a and anti-b antibodies (universal donor)
what are examples of anticoagulants
heparin and warfarin
what is albumin
Protein in the blood; maintains the
proper amount of water in blood
what is an antibody
A specific protein produced by the
lymphocytes in response to bacteria,
viruses, or other antigens
what is an antigen
A substance that stimulates
production of an antibody
what is bilirubin
Orange-yellow pigment in bile; formed
by breakdown of hemoglobin when
RBCs are destroyed
what is coagulation
blood clotting
what is colony-stimulating factor (CSF)
Protein that stimulates growth of
white blood cells
what is differentiation
The change in structure and
function of a cell as it matures;
specialization
what is electrophoresis
A method of separating serum
proteins by electrical charge
what is a erythroblast
a immature red blood cell
what is a erythrocyte
a red blood cell
what is erythropoietin (EPO)
Hormone secreted by the kidneys
that stimulates red blood cell
formation
what is fibrin
Protein that forms the basis of a
blood clot
what is fibrinogen
Plasma protein that is converted to
fibrin in the clotting process
what is globulin
plasma protein
what is a granulocyte
White blood cell with numerous
dark-staining granules
what is a hematopoietic stem cell
A cell in bone marrow that gives
rise to all types of blood cells
what is hemoglobin
blood protein containing iron; carried oxygen in red blood cells
what is an immune reaction
response of the immune system to foreign invasion
what is immunoglobulin
a protein with a antibody activity
what is a lymphocyte
Mononuclear leukocyte that
produces antibodies
what is a macrophage
Monocyte that migrates from the
blood to tissue spaces; as a
phagocyte, it engulfs foreign
material and debris; destroys worn
out RBCs
what is a megakaryocyte
Large platelet precursor cell found
in the bone marrow
what is a monocyte
Leukocyte with one large nucleus;
engulfs foreign material and debris;
becomes macrophage
what does mononuclear mean
Pertaining to cell (leukocyte) with single
round nucleus
what does myeloblast mean
immature bone marrow that gives rise to granulocytes
