👉 Chan fluid, also known as pericardial fluid, is a clear, colorless, and nearly odorless liquid that lubricates the space within the pericardium, the sac surrounding the heart. It serves to reduce friction between the heart's moving surfaces, particularly during cardiac contractions and relaxations, ensuring smooth heart function. The fluid is produced by the pericardial cells and is constantly replenished, maintaining a balance that prevents accumulation and potential complications. Variations in its composition can indicate underlying cardiac issues, making it a valuable diagnostic tool in medical assessments.
