Question

What is the role of the pericardial fluid?

Answer 1

Answer:

There is a very small amount of fluid called pericardial fluid in the pericardial sac. This fluid helps to decrease friction between the pericardial layers. It also allows for smooth movement of the heart when it beats.

Answer 2

$\huge \red{ᴀɴsᴡᴇʀ:-}$

• The heart is surrounded by two layered tissue membrane called pericardium. The space between the two layers is filled with a fluid called pericardial fluid. This fluid protects the heart from external pressure, push, shock and reduces friction during the heart beat and facilitates free heart contraction.
