Anatomy of the Human Heart

This video tutorial provides an in-depth look at the structure of the human heart, focusing on its external features, the mediastinum, and the pericardium. It explains the layers of the heart, including the epicardium, myocardium, and endocardium, and describes the pericardial sinuses. The video also covers the heart's chambers and surfaces, detailing the contributions of each chamber to the heart's overall structure. Finally, it discusses the heart's sulci and their significance in housing major arteries and veins.
