Veins are blood vessels that carry deoxygenated blood back to the heart from various parts of the body, except for the pulmonary veins, which transport oxygenated blood from the lungs to the heart. They have thinner walls than arteries and often contain valves to prevent the backflow of blood, ensuring efficient circulation. Veins play a crucial role in maintaining blood flow and regulating blood pressure within the circulatory system.
