szívbillentyre

Szívbillentyre, often translated as heart valve, refers to the crucial structures within the heart that control the one-way flow of blood. There are four primary heart valves: the mitral valve, the tricuspid valve, the aortic valve, and the pulmonary valve. Each valve functions like a door, opening to allow blood to move forward into the next chamber or blood vessel, and closing tightly to prevent backflow.

The mitral valve is located between the left atrium and the left ventricle. The tricuspid valve sits between the right atrium and the right ventricle. The aortic valve connects the left ventricle to the aorta, the body's main artery. Finally, the pulmonary valve is situated between the right ventricle and the pulmonary artery, which carries blood to the lungs.

Proper functioning of these valves is essential for efficient circulation. When valves do not open fully (stenosis) or close completely (regurgitation or insufficiency), the heart has to work harder, potentially leading to various heart conditions. These issues can range from mild to severe and may require medical intervention, such as medication or surgery, to repair or replace the affected valve. Understanding the role and mechanics of szívbillentyre is fundamental to comprehending cardiovascular health.
