The heart is a main organ . to protect it self from the external effects through cardiac layers which are number in 2 the space between them filled with pericardiacfluid .
The thick layer of the heart wall that contains contractile cardiac muscle tissue is the myocardium. The layer of the heart wall synonymous with the visceral layer of the serous pericardium is epicardium.
Most of the middle layer in the heart wall is composed of cardiac muscle cells. Cardiac muscle cells are also known as cardiomyocytes.

myocardium
Another word for myocardium is the heart muscle. The myocardium is the middle and thickest layer of the heart wall.
The wall of the heart is made up of three layers: the epicardium (outer layer), the myocardium (middle layer made of muscle tissue), and the endocardium (inner layer lining the chambers of the heart). These layers work together to enable the heart to efficiently pump blood throughout the body.
the thinnest wall of the heart is the one supplying heart to the lungs ie : the left side. the thinnest wall of the heart is the one supplying heart to the lungs ie : the left side.
Because there is more pressure on the artery wall (from the heart) than that of the vein.
The main tissue of the heart wall is cardiac muscle tissue, also known as myocardium. This specialized muscle is responsible for the contraction and pumping action of the heart. The heart wall also includes an outer layer called the epicardium and an inner lining called the endocardium, which help protect and support the heart's function.
The endocardium is the innermost layer of the heart wall.
The myocardium (middle layer)
Endometrium wall, but during pregnancy we call it placenta Or myometrium, which is the muscle layer of the uterus.
