Preferred Label : aorta;
Uberon definition : The main trunk of the systemic arterial system that carries blood from the heart to
all the organs and other structures of the body, bringing oxygenated blood to all
parts of the body in the systemic circulation;
Uberon synonym : trunk of aortic tree; trunk of systemic arterial tree;
Uberon narrow term : dorsal aorta;
Uberon Homology note : When vertebrates first appeared, they must have possessed a ventral and dorsal aorta
with aortic arches between them.[well established][VHOG];
Uberon Taxon note : 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;
