Circulation
Your body has a network of blood vessels that work to carry the blood pumped by your heart to your entire body. Your heart and these blood vessels together make up you circulatory system.
Arteries carry blood away from your heart, the largest being your aorta. Your aorta has branches that carry blood to your head, arms and legs, and the organs in your chest and abdomen. The first branches of the aorta are the coronary arteries which run along the surface of your heart to give the muscle its own blood supply, and is often called the ‘crown of your heart’.
Smaller branch arteries feed into even smaller blood vessels called capillaries. Your capillaries allow for oxygen and nutrients to pass into the tissues of your body. Veins then carry blood back to the heart.
