The area between these two layers is known as the pericardial space and normally contains 15 to 50 mL of serous fluid. This fluid protects the heart by serving as a shock absorber and provides lubrication to the heart during contraction. The elastic nature of the pericardium allows it to accommodate a small amount of extra fluid, ro…
