Diagram of the Heart

This drawing includes the arteries which are channels that carry the blood from the left side of your heart to the tissues in your body.

Your arteries branch out and out from your main artery, the aorta, and get smaller and smaller until they are microscopic. The last branches are the capillaries.

The capillaries release oxygen and nutrients and waste products are collected. Your blood continues to flow and starts its trip back to the right side of your heart through your veins.

The inner lining of your arteries is very thin and very smooth and helps the blood to flow easily. This smooth lining is essential to stop your blood from clotting.

Damage to this smooth lining and thickening by atherosclerosis causes heart disease.

Blockages in your arteries weaken the muscles in your heart because they don't get enough nutrients. This is the most common cause of heart disease.
