Estudo macroscópico do coração e pulmão de Mocó

Abstract

For this research, three hearts and three lungs of mocó (Kerodon rupestris) were used, coming from the ESAM Scientific Creatory (School of Agriculture of Mossoró - CEMAS) accredited at IBAMA RN-12-492-004. These organs were measured and macroscopically analyzed. The right and left lungs were macroscopically similar, with the right lung being slightly larger, spongy, multilobed aspect and involved by the visceral pleura. The right lung had a cranial lobe, medium, caudal and accessory subdivided into lateral and medial portion. The left lung showed the cranial lobe subdivided into a cranial and caudal portion, a caudal lobe and an accessory lobe. The anatomical structures of the mocó heart are similar to those of the carnivores, with a rounded apex, a thick interventricular septum and a more pronounced paraconal interventricular branch of the left coronary artery.
