The double-walled membranous sac that encloses the heart is called the pericardium. It consists of two layers: the outer fibrous pericardium, which provides protection and anchors the heart, and the inner serous pericardium, which produces a lubricating fluid that reduces friction as the heart beats. This structure plays a crucial role in maintaining the heart's position and function within the thoracic cavity.
