Características, lobação e segmentação de pulmões dos Quatis

Abstract

The coati (Nasua nasua) is a procionid with a flexible snout, small eyes and ears, which have long canines. They are omnivorous animals with diurnal, terrestrial and arboreal habits, which feed mainly on fruits and small invertebrates. For this work, 3 orthothanized animals were used, coming from the Scientific Creatory (CECRIMPAS) - UNIFEOB authorized by IBAMA as Process: nº 02027.003731 / 04-76. The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. The coatis lungs were collected, analyzed macroscopically to establish the pulmonary lobation, where 4 pulmonary lobes (cranial, middle, accessory and caudal) can be found on the right side of the coatis lung and 2 left lobes (cranial and caudal). Then, the hilum was identified to check the bronchial behavior before penetrating the pulmonary parenchyma, and then the dissection started, determining the bronchipulmonary segmentation of the coatis, where it was found that the bronchial tree of the coatis has 24 segmental bronchi.
