The heart and blood vessels
- Large red vessel = the aorta; large artery that carries blood from of the left ventricle to the arteries of the body
- Large blue vessel = vena cava (includes the superior and inferior vena cava); large vein that empties blood into the right atrium of the heart.

-
Right Coronary Artery (RCA) - supplies blood to the right atrium, right ventricle, bottom portion of the left ventricle and the back of the septum
-
Left Coronary Artery - divides into two branches: the circumflex artery & the left anterior descending artery
-
Circumflex artery - supplies blood to the left atrium and the side and back of the left ventricle
-
Left anterior descending artery (LAD) - supplies blood to the front and bottom of the left ventricle and the front of the septum
-
Coronary veins (in blue) -take oxygen-poor ("deoxygenated") blood that has already been "used" by muscles of the heart and returns it to the right atrium
-
Pulmonary veins - bring oxygen-rich blood back to the heart from the lungs
