Pericarditis is inflammation of which part?

Explanation:
Pericarditis is inflammation of the pericardium, the sac that surrounds the heart—the outer lining. The pericardium consists of an outer fibrous layer and an inner serous layer, and inflammation here is what causes the characteristic chest pain and often a friction rub. This differs from inflammation of the inner lining of the heart (endocardium) or the heart muscle itself (myocardium), or from inflammation of the coronary vessels around the heart.
