How could damage to the heart valves lead to a backup of blood?

Damage to heart valves would cause backflow of the blood meaning the heart would be unable to supply parts of the body with oxygen. In serious cases this could lead to stoke or heart attacks.

If a timing belt on a 92 Geo Metro 1.0L breaks does it do any further motor damage?
Answer: yes it could have bent some valves or damaged a piston with one or more of the valves( could have punched hole in piston or smashed piston so hard that it damaged a bearing)
What act as doors between the chambers of your heart?
The heart does not have doors, but it does have valves that could be thought of as doors. They consist of the semilunar valves (the pulmonary semilunar valve and the aortic semilunar valve). The other two are the atrioventricularvalves (tricuspid and bicuspid valves).
Why don't arteries have valves?
The blood pressure and flow rate in veins is low. When the blood in them is moving upwards (e.g. in the legs) it can stagnate and may have a tendency to flow backwards in the vein. The valves prevent this back flow by closing. The blood pressure and flow rate in arteries is high. Blood flow in the arteries cannot stagnate.
What would happen if the heart did not have any valves?
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.
What is the major function of a valve in a heart?
Valves control the flow of blood. Without them blood could flow backwards.--------------------------Yes, true. Valve would maintain one way traffic for blood right from the heart and to outside parts of the body and form outside to the heart.
If the Timing belt jumped off what could happen to motor on 1998 Chevy tracker?
could cause internal damage to valves and or pistons !
How do the valves between the atria and ventricles control the direction of blood flow?
The heart contains valves to prevent the backflow of blood. The right half of the heart has a "Triscupid Valve" and the left half of the heart has a "Biscupid Valve".
What effects faulty valves would have on a human's blood flow?
valves in the human body are just like water valves, when the heart pumps it pushes blood through veins and arteries. The valves keep the blood in forward motion preventing a back flow. there are valves in the veins but not in the arteries. The valves in the veins keep the unoxygenated blood moving towards the heart to be reoxygenated and keeps it from back flowing into the venus system There are valves in the heart also. there are valves between the upper chambers of the heart (the atria) and the lower chambers (the ventricles. They function the same way, by keeping the blood flowing in the right direction. There are also valve in the heart between the right ventricle flowing towards and thru the pulmonary vein on its way to the lungs and a valve between the left ventricle and the aorta, keeping the reoxygenated blood flowing forward to the rest of the body.
If the timing belt broke on a 1991 Mitsubishi eclipse what damage has it done to the engine or is the engine a contact engine?
There could be bent and/or broken valves. Possible damage to the cylinder head and valve guides. Could be damage to the top of the piston. Or you could br lucky and nothing happened.
What damage if any to engine ford van 1.8 d when cam belt snaps?
I'm not sure on that particular engine. The only damage it could do to the engine piston comes up and hits the valves. On some engines when the timing chain or belt breaks the valves automatically close so there's no damage.
What is the degree of damage anthrax conducts?
Anthrax is an infectious disease from the spore forming bacterium B. anthracis. Anthrax can cause damage to the heart valves and could lead to death.
Why do hearts valves close?
To prevent back flow of blood. Also, the valves alternate when they are opened and closed, such that at certain times, your valves could be shut to allow blood to fill a certain chamber of the heart. This makes it so your heart can pump more blood, since the blood filling causes stretching of the heart wall, which increases the force on blood when it is propelled from the heart. For example, when the heart is beating very fast, there isn't enough time allowed for filling, so the force on the blood isn't as high as it could be.
Could a leech damage your dog?
yes the blood sucking thing could damage your dog because it is sucking out all of the blood from the dogs body. But the dog leech the person could not harm your dog because it is supposed to help animals
What causes an engine to knock when warm?
Could be that your valves are out of adjustment or if you have the nonadjustable valves then it could be a build up of carbon on the valves.
Can a stroke or heart attack cause brainstem damage?
Yes, as it could stop blood flow temporarily to your brain, causing damage.
What could go wrong if a timing belt breaks on a 2001 Chrysler LHS?
Severe internal engine damage is possible. Bent valves likely.
How far can you drive a car with loose tappets?
Indefinitely, but you could create more damage to the valve train the longer you wait to repair/adjust the valves.
