In this cardiovascular physiology lecture, Professor Zach Murphy breaks down the anatomical structures and layered organization of the heart, forming the essential foundation for understanding cardiac function. This lecture is an entry point into how the heart is built—and why that structure is critical to its performance. We begin with an overview of the heart's chambers, valves, major vessels, and septal divisions, followed by a detailed discussion of the three histological layers: the epicardium, myocardium, and endocardium. You’ll learn how each layer contributes to heart function, especially the myocardium, which houses the contractile cardiomyocytes responsible for generating pressure and maintaining circulation. The lecture also covers the pericardial sac, including the fibrous and serous layers, and their roles in reducing friction, anchoring the heart, and preventing overdistension.
