Q

2 functions of B lymphocytes

A

give rise to plasma cells and produce antibodies

31
Q

What do T lymphocytes do?

A

target and destroy foreign cells

32
Q

what do monocytes do?

A

dispose of invading cells and cellular garbage through phagocytes

33
Q

percentage of platelets in whole blood

34
Q

life span of platelets

35
Q

what are platelets involved in?

A

hemostasis (clotting) and repair

36
Q

3 major steps of hemostasis

A
  1. Vascular spasm
  2. Formation of platelet plug
  3. Clot formation
37
Q

another word for vascular spasm

A

vasoconstriction

38
Q

another word for clot formation

A

coagulation

39
Q

what happens during vascular spasms

A

vessels constrict and can stop bleeding

40
Q

vascular spasms result from 2 things:

A
  1. Myogenic Contraction

2. Platelets releasing thromboxane A2

41
Q

When does myogenic contraction occur?

A

it physically activates from damage or pain signals initiate contraction

42
Q

during the formation of a platelet plug, platelets release what?

A

thromboxane a2 and ADP

43
Q

when do platelets swell for platelet plugs

A

when a ruptured vessel exposes proteins

44
Q

How many clotting factors are there?

45
Q

During clot formation, what do platelets synthesize?

A

prothrombin activator

46
Q

the convertion of prothrombin to thrombin in clot formation requires what mineral to be present?

47
Q

in clot formation, thrombin starts conversion of fibrinogen into what?

48
Q

What does fibrin do in clot formation?

A

creates a mesh that traps platelets, blood cells, and other various molecules

49
Q

Hemophilia A is a lack of which clotting factor?

50
Q

the extrinsic path of blood clotthing allows what?

A

bypass some steps

51
Q

If you apply tissue thromboplastin to whole blood, what will happen?

A

activates factor 10, bypassing normal cascade that happens within the body

52
Q

How does asprin, an anticoagulate, affect hemostasis?

A

reduces platelet activation to prevent platelet plug

53
Q

Blood types are determined by the presence of specific…

54
Q

cell protein that stimulates an immune response and sits on the surface of a cell

55
Q

the defense protein in blood that looks for specific antigens

A

antibodies

56
Q

what types of cells produce antibodies?

57
Q

what types of cells attack and destroy tagged cells?

58
Q

What type of antigens does type B blood have?

59
Q

What type of antigens do type O blood have?

60
Q

what types of plasma antibodies do type AB people have

A

neither a nor b anitbodies

61
Q

what type of antibodies do type o blood carriars have?

62
Q

Who are universal donors?

63
Q

Who are universal recipients?

64
Q

How can hemolytic disease of newborns be prevented?

A

at 28 weeks, RhoGAM injection given to mother to destroy any Rh + blood cells in mother’s blood stream

65
Q

bacterial infection of the blood is called

A

septicemia

66
Q

5 symptoms of septicemia

A

flushed skin, chills, fever, rapid heartbeat, shallow breathing

67
Q

blood disorder for reduced oxygen carrying capacity of blood

68
Q

hemorrhagic anemia is caused by

A

blood loss

69
Q

cause of pernicious anemia

A

deficiency in B12

70
Q

renal kidney failure anemia results in what?

A

decrease in red blood cell production

71
Q

type of blood cancer that includes uncontrolled production of white blood cells

72
Q

type of blood cancer that results in easy bruising, anemia or sore bones

73
Q

type of blood cancer that includes impairsproduction of plasma cells

A

multiple myeloma

74
Q

people with multiple myeloma are prone to what?
