Heart Anatomy and Function Assessment

This video tutorial by Meditay covers the anatomy of the heart, focusing on its layers, conducting system, and topography. It begins with an overview of the heart's layers, including the endocardium, myocardium, and epicardium, and explains their structure and function. The tutorial then delves into the heart's conducting system, detailing how electrical impulses are generated and conducted. Finally, it explores the heart's topography, discussing its position relative to the body, skeleton, and other organs.

Which layer of the heart is in direct contact with the blood?
