What is coronary circulation function?

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.

Why is coronary circulation necessary?

The importance of the coronary arteries Because the heart needs oxygen to function properly, the coronary arteries play a vital part in heart health. If they are diseased or damaged, they can reduce blood to the heart, which can lead to heart attack.
