The MUSCLE tissue that forms the walls of the HEART. Myocardial cells are unique in their structure, blending muscle and NERVE structures so they can both contract and conduct electrical impulses. Myocardial cells thus can contract independent of external stimulation. The myocardial fibers of the atria have a different configuration from those of the ventricles. TheCORONARY ARTERIES provide an extensive network to supply blood to the myocardium, which requires about 70 percent of the blood's oxygen. With increasing age, fibrous and fatty tissue tends to infiltrate the myocardium, somewhat reducing its effectiveness.

What is the function of the coronary artery?
The function of the coronary artery is to carry oxygen and nutrients to the myocardium (heart muscle), it does not actually take the carbon dioxide away, (that is the job of the great and small cardiac veins).
