vein
Marble's colored line
A vein is a blood vessel that carries blood toward the heart, distinguished from arteries that carry blood away.
The word extends to similar tube-like structures: the veins in a leaf, the veins in marble or wood grain, a vein of ore running through rock.
Figuratively, a vein is a distinctive quality or strain: a vein of humor, in a similar vein.
To speak in a serious vein is to adopt that tone or mode.
