Detailed explanation-1: -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-2: -Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the inner serous layer.

Detailed explanation-3: -The inner layer of the pericardium is attached to your heart muscle. 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.

Detailed explanation-4: -The pericardium is a tough and layered sac. When your heart beats, it slides easily within it. Normally, 2 to 3 tablespoons of clear, yellow pericardial fluid are between the sac’s two layers. That fluid helps your heart move easier within the sac.

Detailed explanation-5: -The serous pericardium is a layer of serosa that lines the fibrous pericardium (parietal layer), which is reflected around the roots of the great vessels to cover the entire surface of the heart (visceral layer).
