Vias bilíferas no tapir ou anta (Tapirus americanus) | The biliary tree of the tapir (Tapirus americanus)

Portuguese. Os autores estudaram as vias bilíferas do tapir ou anta (Tapirus americanus), após injeção do sistema excretor do fígado de 2 animais, machos e adultos, com látex Neoprene 650 corado, fixação das peças com solução aquosa de formol a 10% e dissecação. O ductus choledocus origina-se a partir da confluência do ramus principalis dexter e do sinister, sendo este animal desprovido de vesícula biliar. O ramus principalis dexter é formado pelos ramus ventralis lobi dextri, ramus medius lobi dextri, ramus dorsalis lobi dextri e ramus processi caudati, os quais se unem por diferentes modalidades. O ramus principalis sinister é formado pelos ramus medius lobi sinistri lateralis, ramus dorsalis lobi sinistri lateralis, ramus lobi quadrati, ramus ventralis lobi sinistri lateralis e ramus lobi sinistri medialis, com diferentes arranjos

English. The biliary tree of two adult, male, tapirs (Tapirus americanus) was injected with latex. After the fixation of the liver with 10% formaldehyde solution the specimens were dissected and photographed. The ductus eloledocus is formed by the confluence of the ramus principalis dexter and sinister, since this species does not possess a vesica fellea. The ramus principalis dexter is made up of the ramus ventralis lobi dextri, ramus medius lobi dextri, ramus dorsalis lobi dextri and ramus processi caudati, which join each other under several arrangements. The same occur with the ramus principalis sinister, formed by the ramus medius lobi sinistri lateralis, ramus dorsalis lobi sinistri lateralis, ramus lobi quadrati, ramus ventralis lobi sinistri lateralis and ramus lobi sinistri medialis.
