Abstract

Introduction: Caracara plancus, popularly known as Carcará, is a bird with broad geographic distribution, occurring from the southern United States to Argentina. Owing to importance of the heart during the flight and the lack of studies of this body in caracaras, this research aimed to conduct the description of the morphology and internal and external morphology heart Caracara plancus. Materials and Methods: Using a magnifying glass (TECNIVAL, SQF-F), precision scale and steel caliper, the heart three caracaras were described morphologically, weighed and measured. Results: The weight of hearts averaged 7,246g ± 0,518g. The mean side-to-side axis was 2,196cm ± 0,085cm and 3,366cm ± 0,036cm the longitudinal axis. In the side wall of the right ventricle was obtained the value of 0,185cm ± 0,035cm in the lateral wall of the left ventricle 0,59cm ± 0,014cm and interventricular septum 0,014cm ± 0.52cm. The heart of Carcará has no anterior interventricular groove; however there is the presence of the posterior interventricular sulcus. Internally, the left ventricle was observed, the presence of atrioventricular valves formed by connective tissue 18 tendinous cords, papillary muscles and a bridge crests. In the right ventricle, the atrioventricular valve was formed by muscle tissue and did not submit chordae, papillary muscles, crests or bridge. Conclusion: The heart of Carcará features in its morphology similar to the hearts of other birds and can be checked one right atrioventricular valve constituted by muscle tissue.
