Discuss the distinct layers within the heart
What will be an ideal response?
The heart wall has three distinct layers: (1) a thin, inner layer, the endothelium, a unique type of epithelial tissue that lines the entire circulatory system; (2) a middle layer, the myocardium, which is composed of cardiac muscle and constitutes the bulk of the heart wall; and (3) a thin, external layer, the epicardium, that covers the heart. The myocardium consists of interlacing bundles of cardiac muscle fibers arranged spirally around the circumference of the heart.
