During systole, both atrioventricular valves (tricuspid and mitral) are closed. The aortic valve is open. During diastole, both atrioventricular valves are open, and the aortic valve is closed.
The semilunar valves are open when blood is being pumped by ventricular contraction. This event is called systole.

The English term for "tahong" is "mussels."
The English term for "suam na tahong" is mussel soup.

Semilunar valves are open when the blood is being pumped. The AV valves are closed when the semilunar valves are open.

after the main safety valves are open
By minute electrical singles produced by the heart itself to open and close the valves.

During systole, both atrioventricular valves (tricuspid and mitral) are closed. The aortic valve is open. During diastole, both atrioventricular valves are open, and the aortic valve is closed.
When the ventricles are relaxed, the semilunar valves are closed, while the atrioventricular (AV) valves are open. This allows blood to flow from the atria into the ventricles. The closure of the semilunar valves prevents backflow of blood from the arteries into the ventricles during this phase.
Atrioventricular (AV) valves open when the pressure in the atria exceeds the pressure in the ventricles. This pressure difference causes the valves to be pushed open from above, allowing blood to flow from the atria into the ventricles. Therefore, it is the pressure from above the AV valves that causes them to open.
Yes, tahong shells, which are the shells of mussels, are biodegradable. They are composed primarily of calcium carbonate, which can break down naturally over time through environmental processes. When disposed of properly, tahong shells can decompose and contribute nutrients to the soil. However, their decomposition rate may vary depending on environmental conditions.
