ANATOMY

Detailed explanation-1: -The semilunar valve located on the right side of the heart is the pulmonary valve of blood. The semilunar valve located on the left side of the heart is the aorta. It prevents the aorta from regurgitating the blood back to the left ventricle.

Detailed explanation-2: -The aortic and pulmonary valves are semilunar valves which separate the ventricles from the aorta and pulmonary artery, respectively.

Detailed explanation-3: -The pulmonary valve or pulmonic valve (PV) is one of the four cardiac valves. It is the semilunar valve that allows blood to exit the right ventricle (RV). It opens during systole and closes during diastole.

Detailed explanation-4: -The semilunar valve prevents blood from re-entering the heart and so deoxygenated blood is pumped through the pulmonary artery where then the blood is oxygenated at the lungs.

Detailed explanation-5: -The pulmonary valve is one of four valves that control blood flow in the heart. It’s between the lower right heart chamber (right ventricle) and the artery that delivers blood to the lungs (pulmonary artery).
