Heart is covered by 2 layered pericardium. Fibrous pericardium
forms a sac surrounding the heart and the roots of its great
vessels.It forms a firm chamber for the heart.Serous pericardium
is a closed serous sac which has been invaginated by the developing heart from above and behind, as a result parietal and
visceral layers formed.Visceral layer are adharent to heart and
roots of great vessels.While parietal layer is outside the visceral
layer and in between these 2 layers is the pericardial cavity
which is filled with serous fluid.

This is the pericardium, a double layer of fibrous tissue with serous fluid between the 2 layers. This allows the layers to slide over each other smoothly when the heart expands and contracts as it beats.
Your spelling makes the rest of your question difficult to decipher. Perhaps you could edit it to improve the clarity?

The sack protecting the heart is the pericardium.

the endocardium is closest to yhe inside...the myocardium is in the middle...this is the muscular layer...then the pericardium is the outside layer..this is sub divided in to two further layers
