Discover the pulmonary valve in this cinematic 3D medical animation from Body Spectra.
The pulmonary valve sits between the right ventricle and the pulmonary trunk. It opens when the right ventricle contracts, allowing oxygen-poor blood to travel toward the lungs. When the ventricle relaxes, the valve closes to help prevent blood from flowing backward.
In this short anatomy journey, discover: ✅ Where the pulmonary valve is located. ✅ How its three semilunar cusps open and close. ✅ Why the valve helps prevent backflow. ✅ How blood travels from the right ventricle toward the lungs.
One fascinating detail: unlike the mitral and tricuspid valves, the pulmonary valve has no chordae tendineae or papillary muscle attachments.
