Vein

A blood vessel that carries blood from the body back to the heart. It's characterized by thinner walls than arteries and often contains valves to prevent backflow. Metaphorically, a vein can also refer to a narrow fissure in rock containing mineral deposits, a streak or pattern resembling a vein, or a particular mood or quality that runs through something. It can even denote a specific style or characteristic in a person.
