32
Q

These Granular Leukocytes compose less than 3% of the total number of white cells, ACIDIC STAINS, and involved with detoxification of foreign proteins entering the lungs and digestive system

A

Eosinophils

33
Q

These Granular Leukocytes make up less than 1% of white cells, act by releasing heparin and histamine at the site of damaged tissue

34
Q

This is a vasoactive agent that increases blood flow to the affected area, and allows the space to fill with fluid

35
Q

This prevents the formation of blood clots helping them to maintain continuous blood flow to damaged tissue

36
Q

Two types of Agranular Leukocytes _____, and _____

A

Lymphocytes, and Monocytes

37
Q

This type of agranular leukocyte composes about 30% of white cells, are the key players in specific immunological defense (immune) system

A

Lymphocytes

38
Q

This type of agranular leukocytes are the largest of the white cells, making up about 5% of the white cell count, act as macrophagocytes digesting large amounts of debris with lysosomal enzymes

39
Q

There are usually ____to _____ thousand leukocytes per cubic mm of blood

40
Q

Neutrophils, Eosinophils, Basophils, and monocytes are examples of this _______ response

A

inflammatory

41
Q

Decrease in the number of circulating white cells

A

Leucopenia

42
Q

Increase in the white blood cell count

A

Leukocytosis

43
Q

Cancer of the leukocytes

44
Q

Cancer of the leukocytes, which were derived from the bone marrow

A

Myeloid Lukemia

45
Q

Cancer of the leukocytes, which are associated with the lymph nodes

A

Lymphoid Leukemia

46
Q

with leukemia the patients resistance to infection is _____ due to the cells being both anatomically and functionally abnormal

47
Q

This refers to the prevention of blood loss

A

Hemostasis

48
Q

Platelets, important for plugging the hundreds of small ruptures that occur throughout the vasculature each day

A

Thrombocytes

49
Q

Thrombocytes are fragments of these LARGE cells that like other blood cells are derived from hemocytoblasts in red bone marrow

A

Megakaryocytes

50
Q

There are around ____ to _____ thousand platelets per cubic mm. of blood

A

150 to 350

51
Q

At the site of a rupture platelets will act as plugs and release this vasoconstrictor that reduces blood flow in a damaged vessel

52
Q

The synthesis of prothrombin in the liver requires this vitamin

53
Q

This factor produced by the liver, circulates in inactive form in the plasma

A

Fibrinogen

54
Q

Damaged vessels release this kind of substance that causes prothrombin to be converted to thrombin (active form)

55
Q

This active form of prothrombin

56
Q

These ions are necessary for the activation of prothrombin to thrombin

57
Q

The activation of prothrombin leads to the conversion of fibrinogen to this,

58
Q

these proteins form long strands that intertwine making a meshwork over a ruptured area, ultimately pulling the ends of the rupture together

59
Q

This is a type of clotting abnormality, is a genetic disease characterized by lack of one of the clotting factors

they don’t bleed more, but they bleed longer which lead to more blood loss

A

hemophilia

60
Q

A stationary clot that actually plugs the vessel itself is called this

61
Q

A wandering clot, one that has become dislodged from the vessel wall is called this

62
Q

Plasma is made up of 92% what

63
Q

Water, salts, hormones, gases, nutrients, waste products and liver proteins make up

64
Q

The three types of liver proteins that make up part of plasma are _____, ______, and _______

A

Albumin, Globulins, and Clotting factors

65
Q

This liver protein aids in maintaining colloidal osmotic pressure, also acts as a CARRIER for certain other blood borne groups

66
Q

This liver protein transports certain fat molecules and vitamins in the blood,

67
Q

A class of globulins that is produced by lymphocytes and act as antibodies

A

Gamma Globulins

68
Q

This kind of liver protein, including prothrombin and fibrinogen, prevents blood loss and aids in hemostasis

A

Clotting Factors

69
Q

The most familiar blood group

70
Q

Universal donor blood group

71
Q

Universal recipient blood group

72
Q

Blood group first discovered in rhesus monkeys

73
Q

what percent of the human population is Rh +

74
Q

The first line of defense against harmful pathogens

A

external barriers of the body, skin, mucous membranes

75
Q

The second line of defense against harmful pathogens

A

internal physiological mechanisms, phagocytosis, inflammation and fever

76
Q

The third line of defense against harmful pathogens is

A

The immune system (Recognize, react, remember)

77
Q

The part of the antigen that serves as the recognition factor

78
Q

This is released by a T helper cell, and stimulates the programmed B cell to divide repeatedly forming clones

A

Interleukin
