Detailed explanation-1: -Your coronary arteries supply blood to your heart. These arteries branch off from the aorta so that oxygen-rich blood is delivered to your heart as well as the rest of your body.

Detailed explanation-2: -The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

Detailed explanation-3: -Coronary circulation is the circulation of blood in the arteries and veins that supply the heart muscle (myocardium). Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated.

Detailed explanation-4: -Where are the coronary arteries located? Your coronary arteries are around and inside your heart muscle. They branch off your aorta, which is the main artery in your body. They start at the aortic root, which is the first part of your aorta that emerges from the left ventricle of your heart.

Detailed explanation-5: -Coronary vascular flow is best described as phasic flow in that the compressive forces of systole counteract the driving force for flow in the coronary circulation and, therefore, the majority of anterograde blood flow to the left ventricle occurs during diastole (Fig.
