The Tucanuçu also known as Tucano toco (Ramphastos toco albogularis - Cabanis, 1862) is a specie of the Piciform Order, Family Ramphastidae that represent one of the symbols of tropical forests. Descriptive studies of its Anatomy are scarce. The Circulatory System is, without a doubt, of fundamental importance for the survival and well being of any animal. Its study is crucial for the knowledge of the individual's biology, especially in the case of wild birds where morphological studies are rare, although important, not only for the knowledge of the biology of the same, but, being able to contribute greatly, for the implantation of conservation and preservation programs for the species and the ecosystem itself. Thus, in the present study, the study and description of the arteries that vascularize most of the Tucanuçu alimentary canal are carried out. The study is divided into three articles - chapters: Cloaca blood supply and Cloacal bag; Origin and distribution of the cranial and caudal mesenteric arteries and Origin and distribution of the celiac artery. The methodology used is based on usual dissection procedures in Macroscopic Anatomy, including the injection of colored latex into the arteries, as a way of better visualizing them. Eight specimens of Tucanuçu (Rhamphastos toco albogularis - Cabanis, 1862), adults, but without defined age, from CETAS-Catalão are used. The results indicate vascular characteristics similar to those described in domestic birds and other wild birds, being almost impossible to identify a vascular pattern, so great is the variability of branches of these vessels. The results are documented in photographs, using a Cyber Shot 7.2 mp camera. Keywords: Anatomy, Arteries. Tucanuçu. Circulatory system
