Question

Quizplus · Accepted Answer

The coronary arteries are the source of blood carried to the capillaries in the myocardium. The coronary artery branches supply oxygen and nutrients to the heart muscle cells, which are essential for the heart to function properly. The coronary sinus and coronary veins are responsible for carrying deoxygenated blood back to the right atrium of the heart. The fossa ovalis is a depression in the interatrial septum that is a remnant of the fetal circulation and has no relevance to the source of blood to the capillaries in the myocardium.
