The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena caves and the coronary sinus ; blood then moves to the right ventricle where it is pumped to the lungs
