The valves have to open to let blood flow into a chamber, and close before the blood flows back. If the valves do not open and close precisely on schedule, or if they fail to open or close completely, the blood will not flow efficiently. This can cause fluctuations in blood pressure, lack of flow to organs, or damage to the muscles of the heart.
For example, if the aortic valve between the heart and the aorta does not close after the left ventricle contracts, there will be back pressure into the ventricle, less blood pumped out of the heart, and lower pressure in the arteries.

∙ 13y agoWhen the AV valve did not completely close during ventricular contraction, the pressure of the blood drives the cusps downward that cause the blood regurgitate (flow back) into the atria when the ventricles contract.
The stroke volume would be decreased and cardiac output would decline. The condition you describe is called a heart murmur.

∙ 12y agoThe blood in your heart would be floating around aimlessly and then when the heart could contract, some of the blood would go in a forward direction, but some of the blood would go backwards. If the valves were working, they would close so when the heart would contract, the blood could not go backwards so it will only go forwards.

∙ 12y agoIf the valves in heart do not close then there will be back flow of blood which would lead to several blood related and heart disorders

What is an endocardiogram?
This is a procedure that checks the status of the heart chambers and valves. Sound waves are used to produce images of the heart and check for any problem in heart muscles or valves. This exam is usually suggested if a doctor believes that the patients blood is being pumped abnormally.
Is there any difference between the heart pumping blood and the heart beating?
Yes the "heart beat" is just the sound of the valves opening and closing, not the sound of the blood being pumped.
Do arteries have valves to allow blood to flow away from the heart?
No, they're aren't any valves in the arteries.
Is a heart attack an accident?
well sometimes it can just happen to anyone for any reason but it can also happen because you are not taking care of your heart or they may also have a blocked artery
Which has less nitrogenous waste the renal vein or the renal artery?
The blood in the Renal Vein:* Is low in oxygen. * Returns to the heart. The blood in the Renal Artery:* Has high amounts of oxygen. * Is pumped from the heart.
When would a murmur occur in the cycle if the av valves were not closing properly?
A murmur would occur during the lubb portion of the cycle if the AV valves were not closing properly. Most heart murmurs do not cause the patient any problems.

What does echocardiography do?
Echocardiography uses sound waves to make images of the heart. These images can show if there are any abnormalities of the heart valves.
What defect causes a heart murmur?
Incomplete closint of any one of the 4 valves may cause a murmur
Is there any difference between the heart pumping blood and the heart beating?
Yes the "heart beat" is just the sound of the valves opening and closing, not the sound of the blood being pumped.
Is there a Bone in a Cows Heart?
No. A cow's heart is comprised of cardiac muscle and epidermis tissue that form the valves and chambers of the heart. Just like in humans, there is no bone in the heart of a cow or any other mammal for that matter.
What will happen to the organism if any of the parts of the heart are injured?

What will happen to the heart if any of the parts damage?
you might die
What will happen to the heart if any parts is injured?
it will stop functioning
