Which valves are semilunar valves that open during ventricular systole?

Explanation:
During ventricular systole, the heart ejects blood by opening semilunar valves to the outgoing arteries. The valves that fit this description are the pulmonic valve, between the right ventricle and the pulmonary artery, and the aortic valve, between the left ventricle and the aorta. These valves open when ventricular pressure exceeds arterial pressure and then close to prevent backflow. The mitral and tricuspid valves are atrioventricular valves that open during diastole to fill the ventricles, not during systole. Therefore, the semilunar valves that open during ventricular systole are the Pulmonary and Aortic valves.
