The principle of complementary structure and function is evident when examining the coverings of the heart. In what way is this relationship evident? a.The pericardium surrounds the heart.b.The epicardium and visceral layer of the pericardium are synonymous.c.The pericardial cavity surrounds the heart.d.The visceral and parietal membranes of the pericardium are smooth and slide past each other, providing a low-friction environment for heart movement.
