what are the 3 layers of tissue that forms the heart?
endocardium, myocardium, pericardium
The heart is made up of three main layers of tissue which are as follows:
1. The Epicardium: This is the outermost layer of the heart which is also known as the visceral layer of the pericardium. It consists of a thin layer of connective tissue. This layer helps in the lubrication of the heart as it contracts and relaxes.
2. The Myocardium: This is the middle and thickest layer of the heart which is made up of cardiac muscle cells. The myocardium is responsible for the contraction of the heart, which pumps blood to the rest of the body. The contraction of the myocardium is coordinated by an electrical conduction system.
3. The Endocardium: This is the innermost lining of the heart which is a smooth layer of endothelial cells. The endocardium lines the chambers of the heart, valves, and large blood vessels that enter and leave the heart. It is essential in the regulation of blood flow and preventing the formation of blood clots within the heart.
