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.
