Note that in FMA an artery is a tree, whereas AEO/JB defines it as a tube; FMA includes a separate class for what it calls the trunk. Classification in this ontology may currently (Jan 2012) represent a mix of both schemes, although we are gradually revising in the direction of the AEO scheme.
Part of the circulatory system composed of blood vessels which carry oxygenated blood away from the heart to the rest of the body.[AAO]
The appearance of Chordata and subsequently the vertebrates is accompanied by a rapid structural diversification of this primitive linear heart: looping, unidirectional circulation, an enclosed vasculature, and the conduction system.[well established][VHOG]
