Something that is veined has a pattern or colouring like that of veins showing through skin. a bronze ashtray shaped like a veined leaf. Having veins or showing veinlike markings. having a pattern of thin lines on the surface
The veins on a leaf are the thin lines on it. the serrated edges and veins of the feathery leaves. Vessel that carries blood to the heart. Except for the pulmonary veins, veins bear deoxygenated blood from capillaries, which converge into threadlike venules and then veins, finally emptying into the venae cavae (see cardiovascular system; vena cava). Blood moves through veins by contraction of the surrounding muscles. Backflow is prevented by valves in most veins' inner layer (tunica intima), which lacks the elastic membrane lining of arteries. The thin middle layer (tunica media) is mostly collagen fibres, and the thick outer layer (tunica adventitia) is mostly connective tissue. See also circulation; varicose vein
blood vessel that returns blood (from the microvasculature throughout the body) to the heart; walls are thinner and less elastic than those of an artery

= any blood vessel transporting blood to the heart Veins are carrying dark red or oxygen-deprived blood in the major body circulation and bright red oxygenated blood in the minor lung circulation
A vein of a particular quality is evidence of that quality which someone often shows in their behaviour or work. This Spanish drama has a vein of black humour running through it
a layer of ore between layers of rock any of the vascular bundles or ribs that form the branching framework of conducting and supporting tissues in a leaf or other plant organ make a veinlike pattern
