Arteries carry oxygen-poor blood from the heart; veins carry oxygen-poor blood back to the heart.
The blood vessel that carries oxygen and nutrient-containing blood away from the heart is an artery. Arteries have thick, muscular walls to withstand the high pressure of blood being pumped from the heart.
The pulmonary veins carry O2 rich blood to the heart.
The coronary arteries are the blood vessels that supply glucose and oxygen to the heart muscle. These arteries branch off the aorta and encircle the heart, delivering nutrients and oxygen-rich blood to support proper heart function.
