Do heart valves require energy to open and close?
no... the force of the blood opens them and they naturally want to stay closed.
What happens to A V valves during ventricular contraction?
As the ventricles of the heart contract the pressure in the ventricles rises beyond that of the atria. This pressure differential causes the AV valves to shut.
What is the function of the valves?
Valves prevent blood from going backward.Valves in general open to allow or close to prevent liquid flow. Heart valves opens to let blood into the heart then close to keep it there so that when the heart muscle contracts and squeezes the blood it is then forced out into the arteries of the body.
What causes the valves to open and close during the heart cycle?
By minute electrical singles produced by the heart itself to open and close the valves.

Do the heart valves open and close due to pressure or volume?
yes
Why does the heart need valves?

Valves of the heart open and close due to?
The valves of the heart open and close due to changes in pressure within the chambers of the heart. When the pressure in a chamber is higher than in the chamber next to it, the valve opens to allow blood to flow through. When the pressure equalizes or reverses, the valve closes to prevent backflow.
Heart valves open and close because of?
well, the valves both bicupsid and tricuspid valve open to let the blood move from the atrium to the ventricle, and close again to prevent back flow of the heart because then blood wont go to the feet and rest of body

valves
What part of the heart opens to allow blood in?

What are heart rhythm abnormalities?
It's when the electrical charge is not going through the heart correctly causing the valves to not open and close in sync.
