Veins carry blood back toward the heart. They have valves to prevent backflow and rely on muscle contractions and breathing to help push blood back to the heart.
The pulmonary arteries are blood vessels that carry oxygen-poor blood from the heart to the lungs for oxygenation.
Arteries carry oxygenated blood away from the heart to the body's tissues, while veins carry deoxygenated blood back to the heart. This key difference in oxygenation levels within the blood is what distinguishes arteries from veins.
The pulmonary vein is the only vein that carries oxygenated blood from the lungs to the heart, while all other veins in the body carry deoxygenated blood back to the heart.
