Detailed explanation-1: -Serous pericardium is the inner layer. It’s further divided into two more layers: the visceral and parietal layers. The serous pericardium helps to lubricate your heart.

Detailed explanation-2: -Serous pericardium: This is the inner layer of your pericardium. It’s actually made of two layers, described below. Your serous pericardium produces pericardial fluid that lubricates your heart as it beats.

Detailed explanation-3: -The inner (visceral) layer of the serous pericardium lines the outer surface of the heart itself. Between the two layers of the serous pericardium is the pericardial cavity, which contains pericardial fluid. It is this fluid that provides lubrication between the two layers, and allows the heart to expand and contract.

Detailed explanation-4: -The pericardium is a double membrane, or sac, that covers the outside of the heart. It contains a lubricating fluid that reduces friction as the heart beats in order to prevent tissue damage.

Detailed explanation-5: -The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures.
