pulmonary valve
(sometimes referred to as the
pulmonic valve
) is the
semilunar valveof the heart that lies between the
right ventricleand the
pulmonary arteryand has three cusps.
Similar to the
aortic valve, the pulmonary valve opens in
ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.
The pulmonary valves, or Semi-lunar valves as they are also known, prevent blood coming from the heart to the lungs from flowing back into the heart, and the blood going from the heart to the rest of the body from flowing back into the heart the wrong way.
It prevents the blood already in the aorta from going back into the heart.
The pulmonary valve controls the movement of blood from the right ventricle to the pulmonary arteries. The aortic valve controls the movement of blood from the left ventricle to the aorta.
valves prevent the backflow of blood.
Yes. The pulmonary valve is a semilunar valve between the right ventricle and the pulmonary trunk.
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.

Pulmonary valve stenosis cannot be prevented
The pulmonary valve
It is the pulmonary valve. Sigmoid is only a synonyme for semilunar (includes pulmonary and aortic valves).
tricuspid valve
pulmonary semilunar valve
I guess you refer to the pulmonary valve stenosis which usually is due to the valve calcification when less blood supply will go from right ventricle of heart to the pulmonary circulation. The right ventricle will be hypertrophied because it's working harder then before.
The pulmonary valve is a semilunar valve that prevents the back flow of blood back from the lungs to the right ventricle.
