• Veins are the blood vessels which carry the deoxygenated blood from all parts of the body towards the heart except pulmonary vein.
• Most of the veins are superficially located in the body i.e., they are present close to the surface of the skin and are visible.
• The flow of the blood in veins is not so fast because it is under low pressure. So, the veins possess thin walls.
• Veins are provided with valves which prevents the backflow of blood and ensures that the blood flows only in one direction, which is towards the heart.
