the valve between the left atrium and left ventricle mitral
the valve between the right ventricle and pulmonary artery pulmonary semilunar
the valve between the left ventricle and aorta aortic semilunar
upper right chamber of the heart; receives deoxygenated blood from the body via the vena cava, and from the heart via the coronary sinus. right atrium
the lower right chamber; receives blood from the right atrium through the tricuspid valve; pumps blood to the lungs through the pulmonic valve via the pulmonary arteries right ventricle
upper left chamber; receives oxygenated blood from the lungs via the pulmonary veins left atrium
lower left chamber; receives blood from the left atrium through the mitral valve; most muscular section of the heart; pumps oxygenated blood through the aortic valve to all parts of the body left ventricle
the right and left coronary arteries branch off from the ______ aorta
encircle the heart like a crown; perfuse the mycardium with oxygen and nutrients coronary arteries

supplies blood to the anterior and lateral wall of the left ventricle, the apex of the left ventricle, and the left atrium left coronary artery
coronary veins empty into the _______ _____ coronary sinus
this subdivision of circulation circulates blood from the left ventricle to all parts of the body and back to the right atrium systemic circulation
this subdivision of circulation circulates blood from the right ventricle to the lungs and back into the left atrium pulmonary circulation
an inherent ability of the heart muscle to contract in a rhythmic pattern automaticity
the ability of the heart muscle tissue to respond to stimulus irritability
the pace maker of the heart SA (sinoatrial) node
the node responsible for stimulating the contraction of the atria SA (sinoatrial) node
the AV node _______ the impulse from the SA node, allowing the atria to complete contraction and the ventricles to fill completely delays
