Explanation:
Detailed explanation-1: -Veins: Unlike arteries, veins don’t have to carry highly pressurized blood, but they do have to carry large volumes of deoxygenated blood back to your heart. Thin, less elastic walls help them handle high volumes and low pressure. Most veins have valves that open and close.
Detailed explanation-2: -Veins have thinner and less muscular walls. This is because veins have a lower level of pressure than arteries. So, their walls don’t need to be as thick to handle the pressure.
