Why do you think the heart needs the coronary arteries to supply it with blood when blood is always flowing through the heart's chambers?

The chambers of the heart function as a pump; they do not utilize the blood that passes through because it is moving far too quickly and turbulently. Blood must run through capillaries at lower speeds/volumes in order to be used by cells. The coronary arteries branch repeatedly to produce a vast network of capillaries that supply the cardiac muscle cells.

What arteries nourish the heart?
The coronary arteries are the blood vessels that nourish the heart. Even though blood goes through the heart, that blood is not the way that the muscle itself picks up nutrients and disposes of wastes.
How is oxygen delivered to the muscular wall of the heart?
Through the coronary arteries.
What is the coronary aretery?
The coronary arteries supply the heart itself with necessary oxygen. When these arteries are blocked, it can cause a myocardial infarction (heart attack). I think that the artery takes it through blood
What phase of cardiac cycle do coronary arteries receive blood flow?
The Coronary Arteries receive blood during Diastole. While the heart is contracting, they are squeezed shut and little blood flows through them.
What is coronary atherosclerosis of native coronary artery?
Coronary Atherosclerosis: is a condition in which the arteries of the heart become clogged with fatty plaque build-up that restricts the amount of blood flow through the arteries while simultaneously causing hardening of the arterial walls. Native Coronary Artery: is an organ for which a transplant or bypass has been implanted
Can you show the arteries of the heart?
It is possible to see the coronary arteries through fluoroscopy.
What is a heart cath?
This is the guided set of wire and tube that you pass through your radial artery or the femoral artery to the opening of the coronary arteries to inject the dye to see the coronary arteries. You can dilate the narrow coronary arteries as well as put the stent there.
Why are blood vessels found in the epicardium?
The blood that flows through the heart chambers doesn't diffuse through the endothelium so it is necessary for the heart to have its own blood supply which are supplied through the coronary arteries on the surface of the heart or epicardium.
What arteries nourish the heart?
The coronary arteries are the blood vessels that nourish the heart. Even though blood goes through the heart, that blood is not the way that the muscle itself picks up nutrients and disposes of wastes.
What information is gained from a cardiac catheterization?
This procedure gathers information such as adequacy of blood supply through the coronary arteries, blood pressures, blood flow throughout chambers of the heart, collection of blood samples, and x rays of the heart's ventricles or arteries.
How is oxygen delivered to the muscular wall of the heart?
Through the coronary arteries.
What is the coronary aretery?

What phase of cardiac cycle do coronary arteries receive blood flow?
The Coronary Arteries receive blood during Diastole. While the heart is contracting, they are squeezed shut and little blood flows through them.
What prevents blood from flowing into the chambers it has already passed through?
valves
Why does blood not flow through the coronary arteries when the heart is contracting?
because it didn't feel like it
What is coronary atherosclerosis of native coronary artery?
Coronary Atherosclerosis: is a condition in which the arteries of the heart become clogged with fatty plaque build-up that restricts the amount of blood flow through the arteries while simultaneously causing hardening of the arterial walls. Native Coronary Artery: is an organ for which a transplant or bypass has been implanted
The heart is what that squeezes blood into the arteries?
Yes, the heart is what squeezes or pushes blood through the arteries.
