Which valve is located between the right ventricle and the pulmonary artery?

Explanation:
Understanding how the heart keeps one-way blood flow is key. The valve at the junction between the right ventricle and the pulmonary artery is the pulmonary valve. It’s a semilunar valve with three cusps that opens when the right ventricle contracts to push blood into the lungs and closes as the ventricle relaxes to prevent backflow. This placement distinguishes it from the valves between the atria and ventricles (tricuspid on the right, mitral on the left) and the valve between the left ventricle and the aorta.
