Pericardial fluid
Pericardial Fluid
Pericardial fluid (pronunciation: per-i-kar-dee-al fluid) is a serous fluid that is secreted by the serous layer of the pericardium into the pericardial cavity.
Etymology
The term "Pericardial fluid" is derived from the Greek words "peri," meaning around, "kardia," meaning heart, and "fluid," which is a Latin term for liquid. Thus, it refers to the liquid that surrounds the heart.
Function
The primary function of the pericardial fluid is to reduce friction between the heart and the pericardium during heartbeats. It also serves as a shock absorber to protect the heart from any sudden impact.
