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.
The fibrous sac of tissue that encloses the heart is the pericardium. It provides protection for the heart.
The ericardium is the fluid filled sac that surrounds the heart and keeps it contained inside the chest.
