What is coronary circulation function?

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.

What organs are involved in coronary circulation?

Coronary circulation is the circulation of blood in the blood vessels that supply the heart muscle (myocardium). Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated.

What are the 3 main arteries in the heart?

The descending aorta. The thoracic aorta. The abdominal aorta.

  • The common iliac arteries. The hypogastric artery. The external iliac artery.
  • What are the most important coronary arteries?

    The heart’s three coronary arteries are not all equal. The most important artery is called the left anterior descending artery (LAD). It feeds blood to the whole front wall of the heart, which represents much more muscle than the area fed by either of the other two coronary arteries.

    What are the most important arteries?

    The major arteries in the body are:

    • The aorta. The largest artery in the body, which connects directly to the left ventricle of the heart.
    • Arteries of the head and neck (carotids)
    • Arteries of the torso (aortic subdivisions, coronaries and subclavian)
