External Anatomy of the Heart (III)

 A. Rather than a fixed value, the weight of the heart can be considered to be 0.3 to 0.45% of the body weight. {11}. A and B. Ventral and dorsal views of an adult heart. With age, epicardial adipose tissue accumulates along the atrioventricular and interventricular sulci and surrounds the epicardial coronary vessels. Accumulation of adipose tissue is also prominent along the acute margin of the heart, which is the sharp angle formed by the anterior and posterior walls of the right ventricle. In the elderly heart some of these features are more pronounced.
