Webster 1828 Edition

Artery

'ARTERY

,
Noun.
[Gr. from air and to preserve or contain; so called, from the opinion of the ancients, that the arteries contained or circulated air. The term was also applied to the trachea or wind pipe, anteria aspera.
A cylindrical vessel or tube, which conveys the blood from the heart to all parts of the body. There are two principal arteries; the aorta, which rises from the left ventricle and ramifies through the whole body; and the pulmonary artery, which conveys the blood from the right ventricle to the lungs, to undergo respiration. An artery is composed of three coats; the outer consists of condensed cellular membrane, and is supplied with numerous blood vessels and nerves; the middle coat consists of circular fibers, generally supposed to be muscular; the inner coat, thin, smooth, and dense, confines the blood within its canal, and facilitates its motion.

Noun

artery ‎(plural arteries)

  1. An efferent blood vessel from the heart, conveying blood away from the heart regardless of oxygenation status; see pulmonary artery.
    • 2013 July-August, Stephen P. Lownie, David M. Pelz, “Stents to Prevent Stroke”, in American Scientist:
      As we age, the major arteries of our bodies frequently become thickened with plaque, a fatty material with an oatmeal-like consistency that builds up along the inner lining of blood vessels. The reason plaque forms isn’t entirely known, but it seems to be related to high levels of cholesterol inducing an inflammatory response, which can also attract and trap more cellular debris over time.
  2. A major transit corridor.
