Detailed explanation-1: -Separates the right ventricle from the pulmonary artery. Opens to allow blood to be pumped from the right ventricle to the lungs (through the pulmonary artery) where it will receive oxygen.
Detailed explanation-2: -The right atrium, now full of oxygen-depleted blood, pumps the blood through the tricuspid valve into the right ventricle. Then the right ventricle contracts to pump blood through the pulmonary valve into the pulmonary artery.
Detailed explanation-3: -The pulmonary valve usually acts like a one-way door from the lower right heart chamber to the lungs. Blood flows from the chamber through the pulmonary valve. It then goes to the pulmonary artery and into the lungs. Blood picks up oxygen in the lungs to take to the body.
Detailed explanation-4: -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.
