    The paired dorsal aortae are connected to aortic arches that in turn arise from the aortic sac. The aortic sac is a primordial dilated vascular channel, lined by endothelial cells and located superior to the truncus arteriosus. It represents the ventral aortae of gill-bearing vertebrates. (two ventral aortae fuse to form the aortic sac which is continuous with truncus arteriosus). Dorsal that the left aortic arch arises from the right ventricle along with the pulmonary artery.
