The tough membrane that lines the four chambers of the heart is called the pericardium. It consists of two layers: the fibrous pericardium, which provides protection and stability, and the serous pericardium, which secretes fluid to reduce friction during heartbeats. Together, these layers help maintain the heart's position within the chest and protect it from infection and trauma.
