What are the functions of the pericardium
Prevents undesired movementPrevents overfilling the heartReduces friction
The pericardium is a double-layered membrane sac that surrounds and protects the heart. Its functions include:
1. Physical protection: The pericardium provides a protective barrier around the heart, shielding it from physical injuries and trauma.
2. Lubrication: The inner layer of the pericardium is called the visceral layer and it secretes a small amount of lubricating fluid that reduces friction between the heart and the pericardium during its contractions.
3. Support: The pericardium holds the heart in place within the chest cavity, protecting it from shifting and moving during physical activities.
4. Immune defense: The pericardium contains immune cells that help fight off infections in the heart tissue through the anti-inflammatory cytokines secretion.
Overall, the pericardium is a vital protective sac for the heart to function effectively, maintain its position, and avoid any potential injury or infection.
