Word Origin and History for veins
c.1300, from Old French veine, from Latin vena "a blood vessel," also "a water course, a vein of metal, a person's natural ability or interest," of unknown origin. The mining sense is attested in English from late 14c. (Greek phleps "vein" had the same secondary sense). Figurative sense of "strain or intermixture" (of some quality) is recorded from 1560s; that of "a humor or mood, natural tendency" is first recorded 1570s.
- Any of the branching blood vessels carrying blood toward the heart. All veins except the pulmonary vein carry dark unaerated blood.
- To supply or fill with veins.
- Any of the blood vessels that carry blood toward the heart from the body's cells, tissues, and organs. Veins are thin-walled and contain valves that prevent the backflow of blood. All veins except the pulmonary vein carry blood with low levels of oxygen.
- One of the narrow, usually branching tubes or supporting parts forming the framework of an insect's wing or a leaf. Veins in insect wings carry hemolymph and contain a nerve. Veins in leaves contain vascular tissue, with the xylem usually occurring on the upper side of the vein (bringing in water and nutrients) and the phloem on the lower side (carrying away food). See more at leaf venation.
- A long, narrow deposit of mineral or rock that fills the void formed by a fracture or fault in another rock. The mineralogy of the host rock surrounding the vein is often altered where it is in contact with the vein because of chemical reactions between the two rock types.
