Artery \Ar"ter*y\, n.; pl. {Arteries}. [L. arteria windpipe,
   artery, Gr. ?.]
   1. The trachea or windpipe. [Obs.] ``Under the artery, or
      windpipe, is the mouth of the stomach.'' --Holland.

   2. (Anat.) One of the vessels or tubes which carry either
      venous or arterial blood from the heart. They have tricker
      and more muscular walls than veins, and are connected with
      them by capillaries.

   Note: In man and other mammals, the arteries which contain
         arterialized blood receive it from the left ventricle
         of the heart through the aorta. See {Aorta}. The
         pulmonary artery conveys the venous blood from the
         right ventricle to the lungs, whence the arterialized
         blood is returned through the pulmonary veins.

   3. Hence: Any continuous or ramified channel of
      communication; as, arteries of trade or commerce.
