Arteries are the main branches and veins are smaller and thinner to transport blood to other parts of the body that arteries aren't.
Two of the primary categories of blood vessels in the body are arteries and veins. Blood channels called arteries transport oxygen-rich blood from the heart to the rest of the body.
Blood channels called veins transport the body's low-oxygen blood back to the heart for reoxygenation.
Blood with more oxygen is carried to tissues by systemic arteries, while blood with less oxygen is carried from the heart to the lungs, where it can be replenished.
Therefore, Arteries are the main branches and veins are smaller and thinner to transport blood to other parts of the body that arteries aren't.
