The myocardium receives its blood supply from the coronary arteries. True or False
Cerrena [4.2K]

Answer:

The statement is true.

Explanation:

The myocardium is the muscle tissue of the heart, a muscle responsible for pumping blood through the circulatory system through contraction. It receives a part of the large volume of blood that passes through the atria and ventricles. A system of arteries and veins (coronary circulation) provides the myocardium with oxygen-rich blood and allows the return of venous or oxygen-poor blood to the right atrium. The right coronary artery and the left coronary artery are the branches of the aorta responsible for the blood supply.
