When there is a problem in blood flow there is the risk of cellular death. In the heart, this complication can be fatal, however, this may not be as problematic in the rest of the body depending on the size or the artery blocked.
When there is a problem in the blood flow of the heart, which is supplied by the coronary arteries, the myocytes of the heart can die. If a smaller artery in heart is blocked, this cell death can even go unnoticed, but will lead to the fibrosis of the heart tissue, not only making it less compliant, but potentially causing problems in the way the heart functions such as re-entry, which can lead to arrhythmias.
In the rest of the body, the blockage of a major vessel can be a big problem. However, if a small blood vessel is blocked the body may have collateral circuits to continue blood supply to tissue. An example of this is the internal thoracic arterty supplying posterior intercostal muscles through the anterior intercostal arteries if the posterior intercostal arteries become blocked.
So, blockage of blood vessels can lead to some big problems, especially in the heart; however, the body does have ways of supplying blood to tissues if they become blocked.
the backflow of blood occurs
There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
The venous system, or "veins" are responsible for bringing blood back from your peripheral body to the right side of the heart, where it is sent to the lungs for reoxygenation. Veins have one way valves that function to maintain a stable pressure in the venous system, while increasing the efficiency of the heart by preventing backflow of blood in between ventricular beats.
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
Valves. There are four in the heart and the rest of the valves are dispersed throughout the body. They function as muscles around the blood vessel contract to move the blood.
Heart valves control the flow of blood into, out of, and within the chambers of the heart. The main function is to let blood flow in one direction only, ensuring that blood does not flow backwards.
A valve fills when the blood flows back, so it cannot flow back too far (into the heart).
Valves function to help keep blood flowing toward the heart. Arteries function to carry blood away from the heart.
Yes. That is 'the' function of the heart valves or for that matter valves.

There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
Veins are thin-walled blood vessels that carry blood to the heart. The valves in veins help prevent backflow. In contrast, arteries have thicker walls and no valves. They carry blood away from the heart.
That is so true! In fact it is the function of the heart valves.

Heart blood vessels is what collects blood and pumps it to the lower chamber. This is what keeps the heart in working function.
