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.
What else can I help you with?
What keep maths blood from flowing back into the chamber of the heart?
There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
Which vessels transport blood toward the heart and have valves?
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.
What is the function of the blood vessels on the outer wall of the heart?
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.
What prevents back flow when the heart is relaxed?
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.
What does the function of the heart valves?
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.
What is the function of valves in blood vessels?
A valve fills when the blood flows back, so it cannot flow back too far (into the heart).
What do the valves in arteries do?
Valves function to help keep blood flowing toward the heart. Arteries function to carry blood away from the heart.
Do both arterial and venous vessels have valves?
No, only venous vessels have valves. Valves in veins help prevent the backflow of blood and aid in promoting blood flow back to the heart. Arterial vessels do not have valves because blood in arteries is under higher pressure and flows away from the heart.
What is the function of the heart blood blood vessels?
Heart-your heart is to pump blood into the blood vessels.Blood vessels-the blood vessels are used to carry bloodBlood- blood carry nutrients to your whole body.
What vessels transport blood toward the the heart and have valves?
veins
What prevent the blood from going in the wrong direction in the heart?
valves
What blood vessels have thin wals and contain valves?
Veins
What keep maths blood from flowing back into the chamber of the heart?
There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
What is the term for a thin-walled blood vessel with valves that carries blood to the heart?
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.
Do the valves in the heart prevent the blood from flowing backwards?
That is so true! In fact it is the function of the heart valves.
What do you think is the mane function of the circulatory system?
blood vessels blood heart
What is the function of the valves which connect the two heart chambers?
Valves prevent the backflow of blood.
