Estudo macroscópico do aparelho respiratório do Quati (Nasua nasua)

Abstract

The coati (Nasua nasua) is a long-snouted procionid, small eyes and ears, which have long canines. Their color varies according to body regions, they are omnivorous animals with diurnal, terrestrial and arboreal habits, which feed mainly on fruits and small invertebrates. For the macroscopic description of the coati respiratory system (Nasua nasua), 5 orthothanged animals were used, which were used in other research carried out at this institution, from the Scientific Creatory (CECRIMPAS) - UNIFEOB authorized by IBAMA as the Process: nº 02027.003731 / 04-76 . These animals were already fixed in a 10% aqueous solution of formaldehyde. The structures were identified, dissected and photo-documented. The respiratory system comprises the lungs in a system of tubes that communicate the lung parenchyma with the external environment. In the coati the nose is located in a nasal plane with a pointed shape and facing top, with its nostrils, it has the dorsal nasal concha and the ventral nasal concha, with dorsal and ventral nasal meatus.The larynx has the four cartilages the arytenoid, cricoid, epiglottis and The trachea is a cartilaginous tube that contains tracheal rings. The lungs are subdivided into lobes by deep interlobar fissures, the right lung is divided into 4 lobes and is larger than the left while the left lung has only 2 lobes. We have concluded so far that the coati respiratory system is similar to the findings described in the literature for domestic carnivores.
