Explanation:
Detailed explanation-1: -The pulmonary valve opens at the systolic phase of the cardiac cycle enabling the deoxygenated blood to be pumped from the right ventricle to the pulmonary circulation.
Detailed explanation-2: -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).
Detailed explanation-3: -Your pulmonary valve closes when your heart relaxes (diastole) and opens when your heart contracts (systole), managing blood flow from your right ventricle to your pulmonary trunk.
