editor note
  • This class is currently a mixed bag, encompassing (1) the entirety of the mammalian aorta together with (2) the developmental and phylogenetic homologs of its segments: the ventral aorta and dorsal aortae.
external definition
  • The main artery of the circulatory system which carries oxygenated blood from the heart to all the arteries of the body except those of the lungs.[AAO]

taxon notes
  • All amniotes have a broadly similar arrangement to that of humans, albeit with a number of individual variations. In fish, however, there are two separate vessels referred to as aortas. The ventral aorta carries de-oxygenated blood from the heart to the gills; part of this vessel forms the ascending aorta in tetrapods (the remainder forms the pulmonary artery). A second, dorsal aorta carries oxygenated blood from the gills to the rest of the body, and is homologous with the descending aorta of tetrapods. The two aortas are connected by a number of vessels, one passing through each of the gills. Amphibians also retain the fifth connecting vessel, so that the aorta has two parallel arches
