Question

Quizplus · Accepted Answer

The coronary arteries are responsible for delivering oxygenated blood to the myocardium via a network of capillaries. The coronary veins and coronary sinus are responsible for returning deoxygenated blood from the myocardium to the right atrium of the heart. The fossa ovalis is a depression in the interatrial septum of the heart and does not play a role in coronary circulation.
