ventricles from the pulmonary trunk and aorta
The pulmonary valve is located between the right ventricle of the heart and the pulmonary artery thus preventing backflow of blood from the pulmonary artery back into the right ventricle.

ventricles
Atrioventricular valves prevent backwards flow of blood inside the heart, i.e. flow from the ventricles back to the atria. Semilunar valves prevent backwards flow of blood into the heart from the aorta (left ventricle) or the pulmonary arteries (right ventricle).
When they are working properly, the four valves of the heart ensure one-way blood flow. The atrioventricular valves prevent backflow into the atria, and the semilunar valves prevent backflow into the ventricles.
When the ventricular pressure exceeds the pressure in the aorta and pulmonary trunk, the semilunar valves are forced open and blood is ejected out. This signals the ejection phase of the cardiac cycle of ventricular systole.
Damage to the left semilunar valve would interfere with blood flow to the aorta.
Valves are important because they prevent the backflow of blood. This is so the fresh oxygenated blood will not be mixed with the deoxygenated blood as well as the blood running from the pulmonary side will not flow back to the aortic side. The valves keep the blood going in one direction, and that keeps the body stable.
All the heart valves close in order to prevent the back flow of blood, including semilunar valve.
Atrioventricular valves prevent backwards flow of blood inside the heart, i.e. flow from the ventricles back to the atria. Semilunar valves prevent backwards flow of blood into the heart from the aorta (left ventricle) or the pulmonary arteries (right ventricle).
Semilunar valves
Valves prevent the backflow of blood, in this case the semilunar valves stop blood flowing back into the heart.
The semilunar valves control the flow of blood from the heart. The aortic semilunar valve controls the flow of blood from the left ventricle to the aorta, and the pulmonary semilunar valve controls the flow of blood from the right ventricle to the pulmonary artery.Pulmonary valve
When they are working properly, the four valves of the heart ensure one-way blood flow. The atrioventricular valves prevent backflow into the atria, and the semilunar valves prevent backflow into the ventricles.
When the ventricular pressure exceeds the pressure in the aorta and pulmonary trunk, the semilunar valves are forced open and blood is ejected out. This signals the ejection phase of the cardiac cycle of ventricular systole.
The pulmonary semilunar valve, also called the pulmonic valve, prevents blood that was ejected out of the right ventricle into the pulmonary artery from flowing back into the right ventricle.
Damage to the left semilunar valve would interfere with blood flow to the aorta.
No, veins have the valves, arteries don't.
No, semilunar valves control the flow of blood out of the heart.
No, the valves that prevent backflow of blood are one-way valves.
