👉 Val fluid, also known as valvular fluid, is a clear, colorless liquid found within the heart's valves. It plays a crucial role in maintaining proper heart function by reducing friction between the valve leaflets as they open and close during each heartbeat. This fluid acts as a lubricant, ensuring smooth and efficient valve movement, which is essential for unidirectional blood flow through the heart chambers. Additionally, valvular fluid helps maintain the structural integrity of the valves and contributes to the overall hemodynamic stability of the cardiovascular system.
