Dehydration because water is lost from the bloodstream erythrocytes remain and become abnormally concentrated

36
Q

Hemorrhagic anemia

A

Bleeding results from kidney failure

37
Q

Hemolytic anemia

A

RBC destruction trauma hemophilia menstruation ulcer

38
Q

Iron deficiency anemia

A

Low oxygen concentration intense pain in oxygen starved tissues

42
Q

Leukopenia

A

When white blood cell is below normal count arsenic mercury poisoning radiation sickness measles mumps and chickenpox polio

43
Q

Leukocytosis

A

Count above 10,000 indicates infection allergy dehydration or emotional disturbances

44
Q

Leukemia

A

Cancer of the hemopoietic tissues produces high number of circulating leukocytes

45
Q

Thrombocytopenia

A

Interference with platelet production which produces dangerous platelet deficiency

46

Two main categories of leukocytes

A

Granulocytes

Agranulocytes

47

A

Megakaryocyte

62
Q

Seven functions of platelets

A

Secrete chemicals stick together to form plugs secrete Clotting factors dissolve blood clots secrete chemicals to sites of information internalize and destroy bacteria secrete growth factors

63
Q

Vascular spasm

A

Immediate protection against blood loss prompt constriction of broken blood vessel

64
Q

Platelet plug formation

A

Pseudopods contract and drawl the walls of the vessel together reduce or stop minor bleeding

65
Q

Coagulation

A

Important for it not to clot in the absence of vessel damage

66
Q

Procoagulants

A

Clotting factors produced by the liver

67
Q

A

Plasma protein

68
Q

Fibrin

A

Sticky protein that adheres to the walls of a vessel

69
Q

Thrombin

A

Converts fibrinogen into shorter strands of fibrin monomer

70
Q

Extrinsic

A

Uses clotting factors from sources external to the blood

71
Q

Intrinsic

A

uses only clotting factors found in the blood itself

72
Q

Clot retraction

A

Adhere to strands of fiber in and contract draws edges of broken vessels together

73
Q

Platelet derived growth factor

A

Fibroblasts invade clot and produce fibrous connective tissue to repair the damaged blood vessels

74
Q

Fibrinolysis

A

Small cascade of reactions with a positive feedback component

75
Q

Plasmin

A

Fibrin dissolving enzyme that breaks up the clot

76
Q

Platelet repulsion

A

Platelets do not adhere to the smooth endothelium of healthy blood vessels

77
Q

Dilution

A

Small amounts of thrombin form in plasma thrombin diluted quickly clot has little chance to form

78
Q

Anticoagulants

A

Thrombin formation is suppressed by anticoagulants that are present in the plasma

79
Q

Hemophilia

A

A family of hereditary diseases characterized by deficiencies of one factor or another

80
Q

Hematoma

A

Masses of clotted blood in the tissues

81
Q

Thrombosis

A

The abnormal clotting of blood in an unbroken blood vessel problematic in old-age

82
Q

Thrombus

A

Clot that grows large enough to obstruct a small vessel or a piece of it may break loose and begin to travel in the bloodstream

83
Q

Embolus

A

Can lodge in a small artery and block blood flow from that point on
