A

WBC

34
Q

Leave the blood and travel by ameboid movement through tissues.

A

WBC

35
Q

protect the body against pathogens and remove dead cells and debris from the tissues by phagocytosis.

A

WBC

36
Q

most common type of white blood cells; Move into other tissues and phagocytize microorganisms and other foreign substances.

A

Neutrophils

37
Q

least common; Release histamine and other chemicals that promote inflammation.

A

Basophils

38
Q

contain cytoplasmic granules that stain bright red with eosin, an acidic stain; Involved in inflammatory responses associated with allergies and asthma.

A

Eosinophils

39
Q

smallest; Production of antibodies and other chemicals.

A

Lymphocytes

40
Q

largest; They enlarge and become macrophages.

A

Monocytes

41
Q

break down phagocytized foreign substances and present the processed substances to lymphocytes, causing activation of the lymphocytes.

A

Macrophages

42
Q

5000-9000 ___ blood cells per microliter of blood.

A

WBC

43
Q

a lower than normal WBC resulting from decreased or destruction of the red marrow.

A

Leukopenia

44
Q

an abnormally high WBC.

A

Leukocytosis

45
Q

cancer of red marrow characterized by abnormal production of one or more white blood cell type, can cause leukocytosis.

A

Leukemia

46
Q

determines the percentage of each type of white blood cells.

A

DIFFERENTIAL WHITE BLOOD COUNT-

47
Q

Smallest part of the body.

A

PLATELETS

48
Q

Fragments of cells as they derived from megakaryocytes.

A

PLATELETS

49
Q

MAJOR FUNCTION IS HOMEOSTASIS!

A

PLATELETS

50
Q

immediate but temporary constriction of a blood vessel when smooth muscle within the wall of the vessel contracts.

A

Vascular spasm:

51
Q

derived from certain prostaglandins.

A

Thromboxanes

52
Q

lining blood vessels released from endothelial (epithelial) cells.

A

Endothelin

53
Q

accumulation of platelets that can seal up a small break in a blood vessel.

A

Platelet plug formation:

54
Q

blood vessel constriction and platelet plugs alone are not sufficient to close large tears or cuts in blood vessels.

A

Blood clotting (coagulation)

55
Q

network of threadlike protein fibers called fibrin.

A

Clot

56
Q

formation of a blood clot depends on a number of proteins found within the plasma.

A

Clotting factors

57
Q

Positive feedback mechanism.

A

Blood clotting

58
Q

Clotting factors are manufactured in the liver.

A

Blood clotting

59
Q

Require vitamin K for synthesis

A

Blood Clotting

60
Q
  • require Ca2+ and the chemicals released from platelets.
A

Blood Clotting

61
Q

attached clot at the damaged or diseased areas of blood vessels.

A

Thrombus

62
Q

thrombus that breaks loose and begins to float through circulations.

A

Embolus

63
Q
  1. Clot begins to condense into a more compact structure.
  2. Platelet contraction > serum is squeezed out of the clot.
  3. Pulls the edges of the damaged blood vessel together.
A

Clot retraction

64
Q
  1. Clots are dissolved as the repair goes on.
  2. Plasminogen: inactive converted to active plasmin w/c breaks down the fibrin.
    Tissue plasminogen activator (t-PA)- can stimulate the conversion of plasminogen to plasmin.
A

Fibrinolysis

65
Q

250,000-400,000

A

Platelet count

66
Q

the platelet count is reduced , resulting in chronic bleeding through small vessels and capillaries.

A

Thrombocytopenia

67
Q

Calculates how long it takes for the blood to start clotting, which normally 9-12 seconds.

A

Prothrombin Time Measurement-

68
Q

a chemical released from injured tissues start the process of clotting.

A

Thromboplastin

69
Q

Transport gases, nutrients, and waste products.
Transport of processed molecules.
Transport of regulatory molecules.
Regulation of pH and osmosis.
Maintenance of body temperature.
Protection against foreign substances.
Clot formation.
