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.
Where in the heart are the bicuspid and tricuspid valves located?

Which heart valve is open under pressure?

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.
