👉 The cole fluid, also known as the pericardial fluid, is a clear, colorless liquid that fills the space between the visceral (solid) and parietal (lining) layers of the pericardium, a double-layered sac surrounding the heart. This fluid plays a crucial role in reducing friction between the heart's moving surfaces during each heartbeat, allowing for smooth and efficient cardiac function. It also serves as a protective buffer, absorbing shocks and preventing excessive pressure from damaging the heart. The volume of cole fluid can vary, but a normal amount ranges from 15 to 250 milliliters, and any significant changes may indicate underlying heart conditions.
