The endocardium is the innermost layer of the heart wall.
This muscular wall of the heart is called the septum. It is a dividing wall that separates the heart into a left and right side. The function of the septum is to prevent the mixing of blood between these two sides.
Septum
The heart's septal wall is called the interatrial septum. The anatomical feature of the heart's septal wall is a crescent-shaped piece of tissue.
Cardiac muscle makes up the wall of the heart. It contracts to pump blood around the body. Smooth muscle is found in the walls of all hollow organs except the heart. There are layers to the wall are myocardium, epicardium and andocardium. The heart is covered by a protective sack called the pericardium. The wall protects the heart and makes it contract and relax.
