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.

∙ 10y agoThe heart gets its blood supply when the ventricles contract and blood leaves through the aorta. The first arteries off the aorta are the coronaries which deliver blood to the heart muscle.

What does a heart attack effeckts in your heart?
If the heart stops (heart attack) the loss of new blood supply causes heart muscle to begin dieing and if recovery isn't started soon you will die. If the heart attack is caused from one or more blocked arteries then the heart tissue depending on blood flow will begin dieing. Quick recovery of blood flow to the heart is necessary as the heart gets it's oxygen and nutrients before the other parts of the body.
Does the upper chambers of the heart receive blood or pushes blood out?
Your right atrium gets the blood supply from the superior and inferior vena cave. The chamber push the blood to the right lower chamber or the right ventricle. The left ventricle gets the blood supply from the lungs and push the same to left ventricle.
What are the soft elastic hollow tubes in the heart?
I think you mean the coronary arteries - the heart muscle itself has many blood vessels that feed it. When a big one gets blocked, the result is a heart attack.
What happens if heart gets bigger?
Certain diseases cause the heart muscle to get big or flabby. In either, the heart can't pump as effectively. This can result in hypertension, Congestive Heart Failure, Heart Attack, etc.
How is blood supplied to the heart and why is this process important?
The heart pumps oxygen-rich blood through arteries which take the blood to muscles. Then when the oxygen is deprived of its oxygen it is pumped back to the heart where it is then sent to the lungs for more oxygen. It then repeats the process. This process is important because your muscles need oxygen to function.
Does the heart have blood in it?
The heart is a muscle and gets its nurisment from blood that flows through it. And it also pumps and circulates blood through it in large vessels and chambers.
When you are fit why can more blood be pumped per min?
When you are fit, your heart muscle is stronger and can pump more blood. The more excercise you do, the stronger your heart muscle gets and the more blood travles through your body.
Why is the human heart able to beat?
It gets a continuous supply of blood rich in oxygen
Why is exersizing good for your heart?
because the heart is a muscle that pumps blood. when you exercise your heart has to pump more blood to the muscles, and just as any other muscle it gets stronger when it has to work hard. and a strong and healthy heart reduces the risk of strokes and improves blood circulation.
What likely happens to the heart rate as the cardiac muscle it gets Stronger?
It starts pumping more blood.
What does a heart attack effeckts in your heart?

What is Heart diseases?
Heart disease is a general term for any heart condition. Most commonly, it refers to problems where the heart gets a reduced blood supply. Heart disease is the most common cause of death in the US and in many other Western countries. Heart disease describes general situation of disorders in the heart, most often problems with the cardiac muscles (including their blood supply) or the valves (damaged or weakened). Mainly anything which leads to changed capacity of heart uptake or discharge of blood (coming to heart and going out from heart), or anything which leads to changed rhythm (timing, order) of contractions. It can also include enlargement of the muscle due to several causes. --- The heart's work is governed by electrical impulses, muscle contractions, its size, and the condition of the chambers and valves. Any of these factors and mechanisms could be abnormal (heart disease).
Chemical in blood signify heart problem?
Usually troponin levels or CPK or CK otherwise known as creatinine levels if elevated could all indicate muscle injury and are released into the blood when muscle gets injured like in heart attacks...or in cases when skeletal muscle gets injured as well like gunshot wounds or tearing of muscles etc.
Is a heart a cardiac muscle?
Unlike other types of muscle, cardiac muscle never gets tired. It works automatically and constantly without ever pausing to rest. Cardiac muscle contracts to squeeze blood out of your heart, and relaxes to fill your heart with blood. Unlike skeletal muscle tissue, its contraction is usually not under conscious control
How do you die by a gun on your heart?
Not sure I understand your question. If you mean by being SHOT in the heart, you can die due to loss of blood- when the brain no longer gets enough blood to supply it with oxygen, it shuts down, you die.
What is actually going on when the heart is pumping?
The heart is a muscle, which expands and contracts. Also, its valves open and close so that blood gets pushed the right direction with each pump.
