48
Q

Heart

A

Upper chambers (2) in the heart

51
Q

Ventricle

A

Lower chambers (2) in the heart

52
Q

Veins

A

Blood vessels that carry blood from the tissues to the heart

53
Q

Pulmonary veins

A

4 veins that return oxygenated from the lungs to the left atrium of the heart

54
Q

Aorta

A

Main artery leaving the left side of the heart and carrying freshly oxygenated blood to the body

55
Q

Heart rate (HR)

A

Number of heart beats per specific time (usually 1 minute)

56
Q

Stroke volume (SV)

A

Volume of blood pumped forward with ventricular contraction (heart beat)

57
Q

Cardiac output (CO)

A

Amount of blood moved per minute (CO=HR * SV)

58
Q

Pulse

A

Wave of pressure created as the heart contracts and forces blood out the left ventricle into the major arteries

59
Q

A

Upper neck

60
Q

A

Groin

61
Q

Radial artery pulse

Cells that carry oxygen to body’s tissues

67
Q

A

Cells that have a role in body’s immune defense mechanism against infection

68
Q

Blood pressure (BP)

A

Pressure that blood exerts against the walls of the arteries as it passes through them (systolic/diastolic)

69
Q

Systolic blood pressure

A

Pressure within the arteries when the heart is contracting

70
Q

Diastolic blood pressure

A

Pressure within the arteries when the heart is at rest

71

Pulse pressure

A

Difference between systolic and diastolic blood pressures

72

Afterload

A

Pressure to be overcome when left ventricle contracts (same as diastolic pressure)

74
Q

Perfusion

A

Flow of blood through body tissues/vessels

75
Q

Hypoperfusion (shock)

A

Inadequate perfusion (flow of blood through body tissues/vessels)

76
Q

Esophagus

A

Tube that extends from the pharynx to the stomach; muscle contractions propel food/liquids through it to the stomach

77
Q

Liver

A

Removes toxins, processes food nutrients, and regulates body metabolism.

78
Q

Enzymes

A

Speed up the rate of specific biochemical reactions

79
Q

Kidneys

A

2 organs that excrete the end products of metabolism as urine and regulate the body’s salt and water content

80
Q

Ureter

A

Tube that carries urine from the kidneys to the bladder

81
Q

Urethra

A

Canal that conveys urine from the bladder to outside the body

82
Q

Respiratory compromise

A

Inability of the body to move gas effectively, can result in hypoxia and/or hypercapia

83
Q

Hypoxia

A

Deficient oxygen concentration in the body

84
Q

Hypercapnia

A

Abnormally high CO2 level in the bloodstream

85
Q

Hypovolemic shock

A

Lack of blood volume; circulating blood volume is not enough to deliver enough oxygen and nutrients to the body

86
Q

Cardiogenic shock

A

Associated with impaired heart function; compromised heart function prevents wastes and nutrients from moving around the body effectively

87
Q

Obstructive shock

A

Results from blocked blood flow back to or through the heart

88
Q

Anaphylactic shock

A

Results from severe allergic reactions

89

90
Q

Neurogenic shock

A

Results from injury to the nervous system

91
Q

Atherosclerosis

A

Disorder in which cholesterol and calcium build up inside the walls of blood vessels, forming plaque, which eventually leads to a partial or complete blockage of blood flow
