Anatomy of the Heart

Arteries

The arteries are major blood vessels connected to your heart.

• The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen.
• The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body.
• The coronary arteries are the other important arteries attached to the heart. They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function.

Veins

The veins also are major blood vessels connected to your heart.

• The pulmonary veins carry oxygen-rich blood from the lungs to the left side of the heart so it can be pumped to the body.
• The superior and inferior vena cavae are large veins that carry oxygen-poor blood from the body back to the heart.
