Differentiate between arteries and veins

Arteries bring blood from the heart to organs and certain parts of the body the blood then goes into veins which take the blood to certain parts of the body, usually the blood in arteries is oxygenated while vein blood is often not

Arteries carry blood (with oxygen) from our heart out to your body, while veins carry blood (without oxygen) from your body to your heart. Arteries are strong, flexible blood vessels that are able to expand (get bigger) and contract (get smaller). They expand as your heart beats, and contract between heart beats. Veins are less flexible than arteries. They have valves (doors) that open and close to let blood through.
