Compare the structure and function of veins and arteries

veins: Thinner and less muscular walls (blood pressure is much lower), larger lumen (moves large volumes of low blood pressure), contains valves (prevents blood from flowing backwards), and less elastic (don't need to stretch)

arteries: Thick and muscular walls (can handle high pressure), small lumen (keeps pressure high), elastic fibers (allows arteries to stretch with each heartbeat), and no valves (blood is pushed forward with high pressure)
