What does the pulmonary valve do?

Answer 1

The

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.

Answer 2

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.

Answer 3

It prevents the blood already in the aorta from going back into the heart.

Answer 4

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.

Answer 5

valves prevent the backflow of blood.
