Arteries are blood vessels that carry blood away from the heart to other parts of the body. Think of them as the superhighways of your circulatory system, delivering oxygen-rich blood (except in the case of the pulmonary artery) to keep everything running smoothly.
Veins, on the other hand, carry blood back to the heart from the body's tissues. This blood is usually deoxygenated (except in the case of the pulmonary vein) and contains waste products that need to be filtered out. Veins are equipped with valves to ensure blood flows in only one direction – towards the heart!
