ventricle
aorta
the main trunk of the arterial system
aortic valve
connects the left ventricle to the aorta
arteries
the largest of the blood vessels that carry the blood away from the heart
arterioles
the smallest arteries that connect with the capilaries
atria
upper two of the four heart chambers; left and right atrium
atrioventricular node
fiber located at the base of the right atrium near the ventricle that carry electrical stimulation to the bundle
basophil
a white blood cell with granules that stain with basic dyes
bicuspid/mitral valve
connects the left atrium to the right ventricle
bundle of His
located at the top of the interventricular septum; carries electrical impulses from the AV node to the Purkinjie fibers
capillaries
the smallest of the blood vessels
cardiac cycle
a complete round of systole and diastole
diastole
relaxation phase of the heart
endocardium
the inner surface of the heart
eosinophil
a white blood cell that stains with certain dyes
epicardium
the outer covering of the heart
erythrocytes
red blood cells, RBC
heart rate
HR; the number of times per minute the heart contracts
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
left atrium
upper left heart chamber
left ventricle
lower left heart chamber
leukocytes
white blood cells; WBC
monocyte
a relatively large WBC
myocardium
the heart muscle, which includes nerves and blood vessels
neutrophil
a mature white blood cell (over 50% of WBC’s)
pericardial sac
another lining of the pericardium closet to the heart
pericardium
serous membrane lining the pericardial cavity
phagocyte
a WBC capable of ingesting bacteria and other foreign matter
plasma
the yellow fluid that makes up more than half of total blood volume
platelets
smallest of the formed elements; important in the coagulation process
pulmonary artery
vessel that carries deoygenated blood from the right ventricle to the lungs
pulmonary valve
valve connecting the right ventricle and the lungs
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-
superior vena cava
large vein that collects blood from the smaller veins of the upper body
systole
contraction phase
tricuspid
valve connecting the right atrium to the right ventricle
venules
small veins
aneurysm
a localized dilation of an artery, cardiac chamber or other vessel
angina pectoris
pain in the chest due to ischemia
cardiac glyosides
drugs used to improve cardiac contraction/output
