0 the main artery (= thick tube carrying blood from the heart) that takes blood to the other parts of the body -- 大動脈，主動脈
For the arterial trunks, this is an easy matter, since the pattern of branching permits ready distinction of an aorta from a pulmonary trunk.
In the descending aorta, the number of elastic lamellae was not significantly different between the different groups.
We speculate that, earlier during development, the aorta was damaged, became inflamed and was repaired, with fibrosis obliterating the elastic tissue.
The arterial trunks both arose from the right ventricle with the aorta in right-sided position.
The aorta arose from the large left ventricle through a competent bicuspid valve.
The aorta arose from the right ventricle supported by a complete muscular infundibulum.
The ascending aorta was also enlarged, measuring 28 mm.
The ascending aorta and aortic valve were small, and the pulmonary trunk and pulmonary valve were reciprocally large.
