Would it be worse to tear an artery or a vein in your leg?

Tearing an artery in your leg would be worse than tearing a vein. Arteries carry oxygen-rich blood away from the heart to the rest of the body, while veins carry deoxygenated blood back to the heart. If an artery is torn, the body will not be able to receive oxygen-rich blood, which can lead to serious complications or even death. Tearing a vein, while still serious, is not as life-threatening as tearing an artery.
