The pericardium, a protective, fluid-filled sac, protects the heart.
The pericardium is crucial for the proper functioning of the heart. Here's a breakdown of its role and components:
- Protection: The pericardium acts as a physical barrier, shielding the heart from infections and trauma.
- Lubrication: The fluid within the pericardium reduces friction as the heart beats.
- Structural Support: It helps maintain the heart's position within the chest and prevents over-dilation.
The pericardium also covers the roots of the major blood vessels extending from the heart, known as the "great vessels," including the aorta.
