Heart Arteries Anatomy

Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. Each artery is a muscular tube lined by smooth tissue and has three layers.

The heart receives its own supply of blood from the coronary arteries.

Heart arteries anatomy. Arteries usually colored red because oxygen rich carry blood away from the heart to capillaries within the tissues. The right coronary artery supplies blood to the right ventricle the right atrium and the SA sinoatrial and AV atrioventricular nodes which regulate the heart rhythm.

The coronary arteries provide the main blood supply to the heart.

Veins usually colored blue because oxygen poor carry blood to the heart from the capillaries. This allows for modulation of vessel caliber and thus control of blood pressure. The coronary arteries also supply the myocardium with oxygen to allow for the contraction of the heart and thus causing circulation of the blood throughout the body.

Arteries are blood vessels that carry blood away from the heart. Blood vessels allow blood to circulate to all parts of the body. Arteries typically have a thicker tunica media than veins containing more smooth muscle cells and elastic tissue.
