part of part of pharyngeal arch 5 pharyngeal arch artery 5 The fifth in a series paired arterial connections between the dorsal and ventral aortae. Aortic arch 5 artery is paired and has a common trunk with aortic arch 6 from the ventral aorta, and drains via a separate branch of the lateral dorsal aorta. Aortic arches 5 and 6 supply the trunk and tail with oxygenated blood.[AAO] The fifth and sixth arches, which come on-line at approximately 2.5 dpf, have a common trunk from the ventral aorta and drain to the midline dorsal aorta via an independent route. The fifth and sixth aortic arches supply the trunk and tail with oxigenated blood.
