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.

These cells can differentiate into endocardium which lines the heart chamber

The heart is divided into four chambers, the left atrium, the left ventricle, the right atrium, and the right ventricle. The two chambers in the upper portions of the heart are the atrium, and the two at the lower portions are the ventricles.
The innermost layer of the heart that is in contact with the blood flowing through its chambers is the endocardium. This layer is a thin membrane that lines the inner surface of the heart chambers and valves, helping to regulate blood flow and prevent clot formation within the heart.
Endocardium is the innermost layer of tissue that lines the chambers of the heart.
Endocardium
The innermost layer of the heart is called the endocardium. It lines the heart's inner chambers and valves, providing a smooth surface for blood flow. The endocardium is continuous with the endothelial lining of blood vessels, including arteries, veins, and capillaries, facilitating seamless circulation throughout the body.
the membrane on the surface of the lung is called the parietal pleura, but the membrance that lines the lungs themselves are called the visceral pleura.
It's endocardium.
The membrane that protects the heart is called the pericardium. It has two layers: - the visceral pericardium (the inner layer which touches the heart) - the parietal pericardium (the outer layer which touches other organs)
