consists of the heart, blood vessels, and blood
cardiovascular system

cardi/o

heart
the double-walled membranous sac that encloses the heart
pericardium, aka pericardial sac
the external layer of the heart and the inner layer of the pericardium
epicardium
means upon
epi-
the middle and thickest of the heart’s three layers and consists of specialized cardiac muscle tissue
myocardium, aka myocardial muscle
consists of epithelial tissue and is the inner lining of the heart
endocardium
means within
endo-
supply oxygen-rich blood to the myocardium
coronary arteries
the two upper chambers of the heart. Receive blood, all blood vessels coming into the heart enter here
atria

ventricles
means ventricle
ventricul

tricuspid valve
valve located between the right ventricle and the pulmonary artery
pulmonary semilunar valve
valve located between the left atrium and left ventricle
mitral valve, aka bicuspid valve
valve located between the left ventricle and the aorta
aortic semilunar valve
receives oxygen-poor blood from all tissues, except the lungs, through the superior and inferior venae cavae
right atrium
pumps the oxygen-poor blood through the pulmonary semilunar valve and into the pulmonary artery, which carries it to the lungs
right ventricle
receives oxygen-rich blood from the lungs through the four pulmonary veins, where blood then flows out through the mitral valve, to the left ventricle
left atrium
receives oxygen-rich blood from the left atrium, then out the aortic semilunar valve and into the aorta
left ventricle
the flow of blood only between the heart and lungs
pulmonary circulation
carry deoxygenated blood out of the right ventricle and into the lungs
pulmonary arteries
