because it didn't feel like it
The Coronary Arteries receive blood during Diastole. While the heart is contracting, they are squeezed shut and little blood flows through them.
Coronary arteries primarily receive blood supply during diastole when the heart is relaxed and filling with blood. This is because during systole, when the heart is contracting to push blood out, the coronary arteries can get compressed which reduces blood flow to the heart muscle.
The heart muscle is supplied with oxygenated blood by the coronary arteries. Along with the oxygenated blood, the arteries also supplies the heart muscle with nutrient-filled blood.
The coronary arteries get their blood directly from the aorta.
The coronary arteries are the blood vessels that nourish the heart. Even though blood goes through the heart, that blood is not the way that the muscle itself picks up nutrients and disposes of wastes.
coronary arteries
The coronary arteries supply blood to the myocardium (heart muscle).
coronary arteries provide blood supply to the heart
Coronary arteries supply blood to the heart itself.
the coronary arteries feed oxygenated blood to the heart muscle where as the coronary veins take the deoxygenated blood back the heart.
