Myokard

The video tutorial explains the structure and function of the heart, focusing on its four chambers and the layers of the heart wall: pericardium, epicardium, myocardium, and endocardium. It highlights the myocardium's role in heart contraction and relaxation, driven by electrical stimuli from pacemaker cells. The myocardium is crucial for pumping blood through the heart and circulation.
