All cardiac veins eventually drain into the coronary sinus for return of the blood from the myocardium to the right atrium.

Question

Quizplus · Accepted Answer

This is true. The coronary sinus is a large vein that lies in the coronary sulcus on the posterior surface of the heart, and it receives blood from cardiac veins draining the myocardium. The blood then flows into the right atrium for oxygenation and distribution to the rest of the body via the pulmonary circulation.
