What collects blood from the myocardium (wastes)?

Explanation:
Blood from the heart muscle returns through the coronary venous system, with the coronary sinus collecting that deoxygenated, waste-rich blood and delivering it into the right atrium. The coronary sinus sits in the posterior part of the heart and is the main collecting vessel for the veins draining the myocardium. The other vessels have different roles: the superior and inferior vena cavae bring blood from the rest of the body into the right atrium, and the pulmonary veins return oxygenated blood from the lungs to the left atrium.
