Leaflet - English Definition & Meaning

Definition

In the context of the heart, a leaflet refers to one of the flaps that make up a heart valve. These leaflets open and close to control blood flow through the heart. Each valve has a specific number of leaflets, like the mitral valve with two and the tricuspid valve with three. They ensure that blood flows in the correct direction and prevents backflow. Think of leaflets as doors that open and shut precisely to regulate movement. They’re thin but strong, enduring constant pressure. Proper leaflet function is essential for efficient heart performance.
