Cardiac Anatomy and Procedures

The video tutorial covers the anatomy and clinical aspects of coronary circulation. It begins with an overview of the heart's external features and surfaces, followed by a detailed explanation of the coronary arteries and veins. The tutorial then describes the inferior surface of the heart and the coronary sinus. Finally, it discusses clinical conditions such as ischemic heart disease and procedures like coronary angiography, angioplasty, and bypass surgery.

What is the primary function of the coronary circulation?

• To supply blood to the digestive system

• To supply blood to the heart muscle
