Question

pericardial fluid... where it is located​

Answer 1

Explanation:

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.
