1. myocardium

2. right –> lungs, left—> all of body (via aorta)

3. pulmonary vein

4. pumps against higher pressure

5. inferior vena cava and superior vena cava –> right atrium

–> right ventricle –> pulmonary artery –> lungs –> pulmonary

vein –> left atrium –> left ventricle –> aorta

6. tricuspid, pulmonic, mitral, aortic. they prevent back flow of blood in the wrong direction.

7. interventricular septum. prevents mixture of oxygenated and deoxygenated blood? but that seems kind of obvious…
