Which chamber receives blood returning to the heart from systemic and pulmonary circulations?

Explanation:
The chamber that receives blood returning to the heart from both circulations is the atria. Blood from the body returns to the right atrium via the superior and inferior vena cavae (and coronary sinus), while blood from the lungs returns to the left atrium via the four pulmonary veins. The ventricles, in contrast, are the pumping chambers that push blood out to the lungs and the rest of the body. The pericardium is the protective sac around the heart, and the myocardium is the muscular wall. So the receiving chambers for venous return are the atria.
