More Physiology of the Myocardium

The video explains the heart's layers, focusing on the myocardium, its high energy demand, and reliance on oxygen. It discusses how the myocardium uses various fuels like glucose and fatty acids, and the consequences of inadequate oxygen supply, leading to conditions like angina pectoris and myocardial infarction.
