The pulmonary valve sits between the right ventricle and the pulmonary artery. It opens during systole to let blood flow into the lungs, then shuts during diastole to prevent backflow. This tricuspid semilunar valve is small but essential. Even slight malformations can lead to pulmonary stenosis or regurgitation, affecting blood oxygenation and heart function.
