Veins. Veins carry unoxygenated blood towards the heart.
the veins supply the heart and the heart pumps the blood around the body
If the blood supply to the heart muscles is blocked, a heart attack is likely.
The coronary blood supply is the arteries which supply the heart itself; in order for the heart to function it needs a good supply of oxygen just the same as any other organ/muscle. Without the coronary blood supply the heart would not be able to pump blood around the body, a disruption in this blood supply would cause a heart attack.
It's the coronary blood supply.
To provide the heart with a blood supply.
Blood
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
The veins carries blood from the body to the heart.
The heart purifies the impure blood and supply the pure blood to all the organs of the body
Oxygen to the heart.
Valves and blood vessels control the flow of blood through the heart. The aorta governs the functioning of these structures by being the main artery in the cardiac system.
The heart is made up of an intricate web of blood vessels (coronary arteries) that ensure an adequate supply of blood rich in oxygen and nutrients.
