right cardiac atrium in dogs

A cardiac atrium that is in the right side of the heart. It receives deoxygenated blood. In mammals, this comes from the superior and inferior vena cava and the coronary sinus, and pumps it into the right ventricle through the tricuspid valve. Every claim on this page comes from the Leumas anatomy graph and carries its source.
