Question

Quizplus · Accepted Answer

The coronary arteries are responsible for carrying blood to the capillaries located in the myocardium (heart muscle). The coronary sinus and coronary veins are responsible for collecting the deoxygenated blood from the capillaries and returning it to the right atrium of the heart. The fossa ovalis is a depression in the interatrial septum that is important during fetal development, but does not play a role in coronary circulation.
