Detailed explanation-1: -Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart.

Detailed explanation-2: -This demand for oxygen is met by the coronary circulation, which is responsible for delivering blood to the myocardium and represents approximately 5% of cardiac output. [1] Adequate blood flow through the coronary vessels is critical to avoid ischemia and maintain the integrity of the myocardial tissue.

Detailed explanation-3: -The correct option is A True. Coronary circulation: Blood circulation to the heart’s muscle through coronary vessels is called coronary circulation. The heart muscle gets a supply of oxygenated blood from coronary arteries.
