formed in red bone marrow, common type WBC
26
fibrinogen, prothrombin
clotting proteins found in plasma
27
serum
plasma fluid after the blood cells and the clotting proteins have been removed
28
diastolic pressure
occurs when the ventricles are relaxed, lowest pressure
29
systolic pressure
occurs when the ventricles contract, highest pressure against walls of arteries

venule
smallest veins that join to form the larger veins
31
capillaries
one epithelial cell in thickness, smallest blood vessels in the body
32
arterioles
smaller, thinner branches of arteries
33
carotid arteries
major arteries are the major arteries that carry blood upward to the head
34
carotid arteries
are specialized conductive fibers located within the walls of the ventricle
35
Bundle of His (HISS)
group of fibers located within the interventricular septum
36
atrioventricular node
which is also known as the AV node, located on the floor of the right atrium
37
sinoartial node
often referred to as the SA node, located in the posterior wall of the right atrium
38
systematic circulation
flow of blood to all parts of the body except the lungs
39
pulmonary veins
carry the oxygenated blood from the lungs into the left atrium
40
pulmonary arteries
carry deoxygenated blood out of the right ventricle and into the lungs
41
pulmonary circulation
the flow of blood only between the heart and lungs
42
aortic semilunar valve
located between the left ventricle and the aorta
43
mitral valve
located between the left atrium and left ventricle
44
pulmonary semilunar valve
located between the right ventricle and the pulmonary artery
45
tricuspid
controls the opening between the right atrium and the right ventricle
46
ventricles
are the two lower chambers of the heart
47
atria
are the two upper chambers of the heart
48
coronary arteries
which supply oxygen-rich blood to the myocardium
49
endocardium
consist of epithelia tissue, is the inner lining of the heart
50
angiostenosis
abnormal narrowing of a blood vessel
51
hemangioma
tumor made up of newly formed blood vessels
52
hypoperfusion
deficiency of blood passing through an organ or body part
53
arteriostenosis
abnormal narrowing of an artery
54
arteriosclerosis
disease characterized by thickening and the loss of elasticity of arterial walls
55
deep vein thrombosis
condition of having a thrombus attached to the interior wall of a deep vein

peripheral vascular disease
disorder of blood vessels that are located outside of the heart and brain
57
hemochromatosis
genetic disorder of intestines absorb to much iron
58
polycythemia
abnormal increase in number of red cells
59
thromocytosis
abnormal increase in the number of platelets in circulating blood
60
hyperlipidemia
general term used to describe elevated levels of cholesterol and other fatty substances in the blood
61
thalassemia
inherited blood disorder that causes mild or severe anemia
62
hypertension
elevation of arterial blood pressure to a level that is likely to cause damage to the cardiovascular system
63
hypotension
lower-than-normal arterial blood pressure
64
angiography
radiographic study of the blood vessels after injection of contrast medium
65
digital subtraction angiography
combines angiography with computerized components to clarify the view of area
66

diagnostic procedure to image the structure of the blood vessels and the flow of blood through these vessels
67
holter monitor
portable electrocardiograph that is worn by an ambulatory
