Heart Coronary circulation (OLD version)

The video tutorial explains the coronary circulation system, focusing on the coronary arteries and cardiac veins. It details the right and left coronary arteries, their branches, and the concept of heart dominance. The innervation of coronary arteries by sympathetic and parasympathetic systems is discussed, highlighting their effects on vasodilation and vasoconstriction. The tutorial concludes with an overview of cardiac veins and the coronary sinus, emphasizing their role in draining deoxygenated blood from the heart.
