Veins are the blood vessel type that conveys blood from the systemic circulation back to the heart. They carry deoxygenated blood, except for the pulmonary veins, which transport oxygenated blood from the lungs to the heart. Veins have thinner walls and larger lumens than arteries, allowing them to accommodate varying volumes of blood. Valves within veins help prevent the backflow of blood as it moves toward the heart.

What is the structural difference between pulmonary vessel walls and systemic vessel walls?

One role of the systemic cirulation to deliver oxygen rich blood to where it is needed. That is to say that cells need oxygen to do their work, the brain to think and the muscles to contract. They get their oxygen from the systemic circulation. But blood in the systemic circulation got its oxygen from being in the pulmonary circulation.
