coronary arteries
The coronary arteries carry oxygenated blood to the heart itself. These arteries supply the heart muscle with oxygen and nutrients.
Coronary arteries are the vessels that provide blood supply to the heart muscle itself. If they are blocked or damaged, a heart attack may result.
Heart attacks or myocardial infarctions are caused by blockages of the coronary arteries or the blood vessels that provide the blood supply to the heart muscle itself.
It contracts, so the blood flows into the arteries. Then, the cardiac muscle relaxes, so the blood flows back. The backflowing blood fills the valves in the arteries, so it cannot flow back into the heart itself. While the cardiac muscle relaxes, new blood flows into the ventricles and atriums from other veins.
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 Arteries
It contracts, so the blood flows into the arteries. Then, the cardiac muscle relaxes, so the blood flows back. The backflowing blood fills the valves in the arteries, so it cannot flow back into the heart itself. While the cardiac muscle relaxes, new blood flows into the ventricles and atriums from other veins.
The coronary arteries because they supply fresh blood to the heart's own muscle. The heart stops pumping if its muscle wall doesn't get enough blood. The coronary arteries are what supply blood to the heart itself and they are pretty small and narrow- they can't handle even a small clot.
