Where is pericardial fluid found?
The pericardium is a two-layered, sac-like membrane that surrounds the heart. Pericardial membranes produce pericardial fluid, a liquid that
sits between the pericardium's membranes
. The fluid acts as a lubricant for the movement of the heart, reducing friction as the heart pumps blood.
What are the 3 layers of pericardium?
The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers,
the fibrous pericardium, the parietal pericardium, and the visceral pericardium
. The parietal and visceral pericardia together form the serous pericardium.
