right atrium
Valve between the left atrium and left ventricle.
mitral valve
Veins flow ______ the heart.
into

Interventricular septum
vessels that carry deoxygenated blood back to the heart; there are 2!
superior and inferior vena cava
Deoxygenated blood flows through this side of the heart.
Right
Internal layer of the heart wall, lines heart chambers.
