Question

which part of the heart is covered by thickness

Answer 1

The part of the heart that is covered by thickness is the myocardium. The myocardium is the thick, muscular middle layer of the heart wall, responsible for the contraction and pumping action of the heart. It is significantly thicker in the ventricles than in the atria because the ventricles need to generate more force to pump blood out of the heart and into the circulation. The left ventricle, in particular, has the thickest myocardium because it pumps blood to the entire body, whereas the right ventricle pumps blood to the lungs.
