the heart is a muscle, and every muscle needs blood because the blood caries oxygen to the cells of that muscle which is then converted into energy and this is what makes our bodies work. your heart however is a special muscle that pumps your blood to all of the muscles in your body.

∙ 13y agoThe chambers are not porous (so that they can contain the pressure of the pumping action). Therefore the blood in the chambers is not available to the heart muscles and these must be provided with their own blood supply outside the heart.

∙ 11y agoThe heart functions non-stop during one's lifetime and therefore requires a constant blood supply to provide its tissues with the necessary oxygen and nutrition to keep pumping.

How does a blocked artery cause less oxygen to reach the heart?
Arteries carry blood, oxygenated by the lungs, to the cells of the body. Since the heart is a large muscle, its cells need oxygen too. When one of the arteries supplying the heart with oxygenated blood is blocked ("occluded") the oxygen cannot reach the cells supplied by that artery.
How is blood different when returning to the heart?
when blood is returning to the heart quite oxygenated as the heart need constant supply of blood. but i am not sure about this so you way to use a range of other sources to get a more reliable awnser.
Why must you massage towards the heart?
If you massage towards the heart it promotes venous blood return back to the hart so that it may get re-oxygenated. Arteries are lined by smooth muscle and they have valves where as the veins are a more passive system, so sometimes they need help.
What is the septum of the heart?
the septum seperates the left and right ventricles
What is the purpose of the coronary artery and what happens if there is a blockage?
Coronary artery bypass graft surgery (also called coronary artery bypass surgery [CABG] and bypass operation) is performed to restore blood flow to the heart. This relieves chest pain and ischemia, improves the patient's quality of life.

How those the heart help the body?
It pumps oxygenated blood to the body, which we need to survive.
How does the structure of cardiac muscle help it perform its function?
Cardiac muscle is also an involuntary muscle. (Do you need to tell your heart to beat?) It is a specialized kind of muscle found only within the heart. This muscle pumps blood through the body. The average person's heart beats more than 4,000 times in an hour (figuring on an average of 70 beats per minute), so, by time you turn 70, your heart will beat some two-and-a-half billion times. Cardiac muscle, like smooth muscle, does not tire.
Why is it important for your heart to keep oxygen- rich blood separate from oxygen - poor blood?
It is important to keep oxygen rich blood separate from oxygen poor blood in your heart to prevent damage to the heart muscle, angina attacks or even myocardial infarction as heart muscle will dye without good oxygenated blood flow.
Why does the heart require its own special ciculation system?
The heart is a muscle and muscle require oxygenated blood, it is not a special circulatory system it is a extension of the main system. While you might think the heart would have no problem getting enough oxygen-rich blood, the heart is no different from any other organ. It must have its own source of oxygenated blood. The heart is supplied by its own set of blood vessels. These are the coronary arteries. There are two main ones with two major branches each. They arise from the aorta right after it leaves the heart. The coronary arteries eventually branch into capillary beds that course throughout the heart walls and supply the heart muscle with oxygenated blood. The coronary veins return blood from the heart muscle, but instead of emptying into another larger vein, they empty directly into the right atrium.
What sends oxygenated blood from heart to body?
The circulatory system which includes the heart and arteries carry oxygenated blood to the body cells.
How is blood different when returning to the heart?
when blood is returning to the heart quite oxygenated as the heart need constant supply of blood. but i am not sure about this so you way to use a range of other sources to get a more reliable awnser.
Why do blood cells need to travel back through the heart to the lungs?
So as to get OXYGENATED by process of OXYGENATION(and not oxidation).
Is an Artery a blood vessel that carries blood away from the heart to the body?
Generally speaking, arteries carry oxygenated blood while veins carry de-oxygenated blood. Cells in your body need the oxygen carried by arteries, so the heart pumps it away from the heart, towards the other organs in your body.After the organs use the oxygen in the blood, it is carried back to your heart and lungs by the veins.
Why must you massage towards the heart?
If you massage towards the heart it promotes venous blood return back to the hart so that it may get re-oxygenated. Arteries are lined by smooth muscle and they have valves where as the veins are a more passive system, so sometimes they need help.
Does heart need lungs?
Of course the heart needs lungs. without them the heart wouldn't be able to pump because it needs to take in oxygenated blood and pass through the heart and become oxidized.
What is the septum of the heart?
the septum seperates the left and right ventricles
