Resumo
Studying the behaviour of the ductus choledocus of the ductus cysticus and the systematization of the ramus principalis dexter, in 50 livers of adult male ovines of the Merino race, the A. arrived to the following conclusions: 1 the ductus choledocus always free from tributaries, is shown in 48 parts, being 96% of them constituted by the union of the ramus principalis dexter, and ramus principalis sinister (4.0% ), in two cases by the triplice convergence of dorso medialis and ventrolteralis roots of ramus principalis dexter plus the ramus principalis sinister. 2 the ductus cysticus, free in of its preparations (84.0%) is seen when receives tributaries which come from the lobus quadratus. The eight (16.0%) which are left integrate themselves in the system of ramus principalis dexter. 3 the system of ramus principalis dexter is formed by ramus medialis lobi dexter, ramus dorsalis lobi dextri, ramus processi caudati, ramus lateralis lobi dextri, ductus cysticus, rami intermedii lobi dextri and innominate ducts from the lobus dexter (medial, dorsal and lateral territories ), the lobus caudatus (pars supraportalis, processus papillaris, pons and processus caudatus) and lobus quadratus.Estudando o comportamento do ductus choledocus, do ductus cysticus e a sistematização do ramus principalis dexter, em 50 fígados de ovinos, machos, adultos, da raça Merino, o A. obteve, entre outras, as seguintes conclusões: 1 O ductus choledocus, sempre livre de tributários, mostra-se, em 48 peças (96,0%), constituído pela união do ramus principalis dexter e ramus principalis sinister e, em 2 casos (4 ,0% ), pela tríplice convergência das raízes dorsomedial e ventrolateral do ramus principalis dexter, mais o ramus principalis sinister; 2 O ductus cysticus, livre em 42 preparações (84,0%) e visto a receber tributários vindos do lobus quadratus nas 8 restantes (16,0%), integra-se sempre ao sistema do ramus principalis dexter; 3 O sistema do ramus principalis dexter é formado pelo ramus medialis lobi dextri, ramus dorsalis lobi dextri, ramus processi caudati,ramus lateralis lobi dextri, ductus cysticus, rami intermedii lobi dextrie coletores inominados do lobus dexter (territórios medial dorsal e lateral), do lobus caudatus (pars supraportalis, processus papillaris, pons e processos caudatus) e do lobus quadratus.
