because all your body needs blood to be able to function
The heart muscle is supplied by blood vessels called coronaries.
Yes.
coronary arteries
Capillaries deliver blood tot he muscle of the heart. In fact, it is about 1 capillary per contractile cell of the heart. These cells require a rich blood supply since they are very active cells.
It delievers the blood supply to the heart muscle itself
Of course heart muscles need a blood supply for the cellular respiratory process as the blood carries the final electron acceptor oxygen which is key to oxidative phosphorylation in humans.
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.
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
Blood is oxygenated in the lungs travels through the pulmonary veins into the heart. The heart muscle itself receives oxygenated blood through through the coronary arteries that branch off from the aorta.
True, a myocardial infarction is the term for a heart attack and is caused by a lack of blood supply to a part of the heart, causing damage to the heart muscle.
The coronary arteries supply blood to the myocardium (heart muscle).
