The pulmonary arteries and the pulmonary veins are the vessels of the pulmonary circulation; which means they are responsible for carrying the oxygenated blood to the heart from the lungs and carrying the deoxygenated blood from the heart to the lungs. Pulmonary veins are large blood vessels that receive oxygenated blood from the lungs to delivery to the rest of the body.
- Arteries carry blood away from the heart.
- Veins carry blood toward the heart.
- Arteries carry blood rich in oxygen, oxygenated.
- Veins carry blood with carbon dioxide, deoxygenated.
