Heart valves in motion: tricuspid & pulmonary valves in 3D 🫀 Your heart beats 100,000 times a day, pumping blood through a network of valves that ensure unidirectional flow and prevent backflow. Two of these essential valves—the tricuspid and pulmonary valves—work together to keep oxygen-poor blood moving toward the lungs for oxygenation. Let’s take a closer look at their function and importance: Tricuspid valve ✔️ Located between the right atrium and right ventricle ✔️ Opens to allow blood to
