aorta
the main trunk of the arterial system
28
aortic valve
connects the left ventricle to the aorta
29
arteries
the largest of the blood vessels that carry the blood away from the heart
30
arterioles
the smallest arteries that connect with the capilaries
31
atria
upper two of the four heart chambers; left and right atrium
32
atrioventricular node
fiber located at the base of the right atrium near the ventricle that carry electrical stimulation to the bundle
33
basophil
a white blood cell with granules that stain with basic dyes
34
bicuspid/mitral valve
connects the left atrium to the right ventricle
35
bundle of His
located at the top of the interventricular septum; carries electrical impulses from the AV node to the Purkinjie fibers
36
capillaries
the smallest of the blood vessels
37
cardiac cycle
a complete round of systole and diastole
38
diastole
relaxation phase of the heart
39
endocardium
the inner surface of the heart

eosinophil
a white blood cell that stains with certain dyes
41
epicardium
the outer covering of the heart
42
erythrocytes
red blood cells, RBC
43
heart rate
HR; the number of times per minute the heart contracts
44
hemoglobin
the protein that gives blood its color; Hb

inferior vena cava
large vein that collects blood from the smaller veins of the lower body

leukocytes
white blood cells; WBC

myocardium
the heart muscle, which includes nerves and blood vessels
51
neutrophil
a mature white blood cell (over 50% of WBC's)
52
pericardial sac
another lining of the pericardium closet to the heart
53
pericardium
serous membrane lining the pericardial cavity
54
phagocyte
a WBC capable of ingesting bacteria and other foreign matter
55
plasma
the yellow fluid that makes up more than half of total blood volume
56
platelets
smallest of the formed elements; important in the coagulation process
57
pulmonary artery
vessel that carries deoygenated blood from the right ventricle to the lungs
58
pulmonary valve
valve connecting the right ventricle and the lungs
59
pulmonary veins
vessels that carry oxygenated blood from the lungs to the left atrium

Rh factor
an antigen; first discovered in the Rhesus monkey. People are either Rh+ of Rh-
61
superior vena cava
large vein that collects blood from the smaller veins of the upper body
