Abstract

The aim of this study was to describe the behaviour of the aorta artery, to focus its origin, trajectory, and destiny of its ramifications. There were used ten females and males turtles. We canalized the common carotid arteries through which we introduced a physiological solution to remove obstruction from the vascular system, than a colored solution of Neoprene Latex “450” was injected. We fixated the material in Formaldehyde 10% for a period of 96 hours. After this, we removed the skull from its insertions, showing the viscera and individualizing the aorta artery. We observed that the right and left aortic arch unite in a point right after its origin in the heart. The left aortic arc send the gastric artery, celiac artery and the cranial mesenteric artery which arise cranial to the point of union of the aortic arcs. It still originates a celiac artery that provides the cranial pancreaticduodenal artery. Right after, the trunk formed by the union of the two aortic arch is denominated the aorta artery and from it originates the renal, epigastrics, external iliac, internal iliac and the caudal arteries, that is a thin segment of the final portion of the aorta. The aortic right arch does not emit any branch before its union with the left aortic arch, so the main visceral branches comes from the left aortic arch or directly from the aorta artery.
