Resumo
It was studied, by dissecation, the biliary ducts on 36 livers removed from adult Nelore cattle. The results obtained were: 1) The ductus choledocus is formed by the convergence of the ductus hepaticus and ductus cysticus (96.7%) or by the convergence of the ramus principalis dexter, ramus principalis sinister and ductus cysticus (3.3%); 2) The ductus hepaticus is caracterized in 96.7% of the cases and it receives tributaries (40.0%) from the lobus quadratus (3.3%), from the lobus dexter, lobus caudatus and lobus quadratus (13.3%), from the lobus dexter and lobus quadratus (6.7%) or from the lobus dexter (6.7%); 3) The ductus cysticus also receives tributaries (83.3%) from the lobus dexter and lobus quadratus (43.3%), from the lobus quadratus (20.0%), from the lobus dexter (16.7%) or from the lobus dexter, lobus caudatus and lobus quadratus (3.3%); 4) The vesica fellea is too big in these animals and it receives some hepatocystic ducts (53.3%) from the lobus dexter (30.0%), from the lobus quadratus (13.3%), from the lobus quadratus and lobus sinister (3.3%), lobus dexter, lobus quadratus and lobus sinister (3.3%) or from the lobus quadratus, lobus caudatus and lobus dexter (3.3%); 5) Some livers (73.3%) have showed anastomosis between the ramus principalis dexter or the ramus principalis sinister and the ductus cysticus or the vesica fellea. This anastomosis and the hepatocystiEstudou-se, mediante dissecção, o sistema escretor do fígado de 36 fêmeas adultas de bovinos daraça Nelore, concluindo-se que: 1) 0 ductus choledocus é formado pela convergência do ductus hepaticus e ductus cysticus (96,7%) ou, raramente (3,3%) pela tríplice confluência do ramus principalis dexter, ramus principalis sinister e ductus cysticus; 2)o ductus hepaticus, caracterizado em 96,7% dos casos, recebem alguns deles (40,0%), tributários vindos apenas dolobus quadratus (3,3%), concomitantemente do lobus dexter, lobuscaudatus e lobus quadratus (13,3%), simultaneamente do lobusdexter e lobus quadratus (6,7%) e somente do lobus dexter (6,7%);3) o ductus cysticus recebe tributários, na maior parte dos casos (83,3%) procedentes concomitantemente do lobus dextere lobus quadratus (43,3%), apenas do lobus quadratus (20,0%),somente do lobus dexter (16,7%) e simultaneamente do lobusdexter, lobus caudatus e lobus quadratus (3,3%); 4) a vesica fellea recebe numerosos duetos hepatocísticos, na maior parte dos casos (53,3%), oriundos apenas do lobus dexter (30,0%), somente do lobus quadratus (13,3%), concomitantemente do.lobus quadratus e lobus sinister (3,3%), simultaneamente do lobus dexter, lobus quadratus e lobus sinister (3,3%) e ao mesmo tempo dolobus quadratus, lobus caudatus e lobus dexter (3,3%); 5) na maior parte das glândulas (73,3%) foram observados tractos anastomóticos a inte
