Understanding the Structure and Function of the Heart
Explore the intricate details of the heart, including its chambers, external features, myocardium, valves, and fibrous skeleton. Delve into the layers of the heart wall, the pericardium, and the fibrous skeleton. Learn about the different layers of the myocardium in the atria and ventricles, as well as the roles of heart valves in maintaining proper blood flow. Discover the complexities of valve diseases and endocarditis.
