arteries (red) Take oxygen and nutrients away from the heart, to your body tissue. Veins (blue) bring oxygen-poor blood back to the heart. Arteries start in the aorta, the large arteries leave the heart. They carry oxygen-rich blood from the heart to all tissues in the body.

Do arteries always carry oxygen-rich blood?

Arteries usually carry oxygenated blood Veins usually carry deoxygenated blood. This is the case most of the time. However, pulmonary arteries and veins are an exception to this rule. The pulmonary veins carry oxygenated blood to the heart, and the pulmonary arteries carry deoxygenated blood away from the heart.

Who carries oxygen-rich blood?
