pericardial sac

a fluid-filled membrane that surrounds and protects the heart

pulmonary artery

carries deoxygenated blood from the right ventricle to the lungs for oxygenation

pulmonary vein

carries oxygenated blood from the lungs to the heart

coronary artery

supplies oxygenated blood to the heart muscle

coronary vein

drains deoxygenated blood from the heart muscle

anterior vena cava carries oxygen poor blood from upper part of the body into the right atrium

posterior vena cava

collects blood from lower part of body to return to heart

left & right auricles

external, ear-like flaps on the atria of the heart

heart valves

tricuspid, pulmonary, mitral (bicuspid), and aortic

left atrium

receives oxygenated blood from the lungs through the pulmonary veins

left ventricle

receives deoxygenated blood from the body via the superior and inferior vena cava

right atrium

the right upper chamber of the heart that receives blood from the venae cavae and coronary sinus

right ventricle

pumps deoxygenated blood to the lungs through the pulmonary artery

foramen ovale
