A contribution to the study of the intra and extra-hepatic ducts in chickens (Gallus gallus domesticus)

Abstract

The sistematization of the biliary ducts was carried out in 30 livers obtained from adult males (Gallus gallus domesticus - ANAK lineage). The results showed that the ductus hepatoentericus is integrated by nominate ducts from: the lobus sinister and from the dorsal and mediodorsal territories of the lobus dexter (56.7%); the lobus sinister and from the dorsal, mediodorsal and ventral territories of the lobus dexter (16.7%); the lobus sinister and the lobus dexter (6.7%); just once from the dorsal and mediodorsal territories of the lobus dexter (3.3%). The ductus cysticoentericus also drains different territories of the gland, which are: the medioventral and ventral territories of the lobus dexter (56.7%); the mediodorsal, medioventral and ventral territories of the lobus dexter (16.7%); only the medioventral territory of the lobus dexter (16.7%); the lobus sinister and the medioventral and ventral territories of the lobus dexter (3.3%). Nominate and inominate
ducts flow to the vesica fellea (53.4%), to the ductus cysticus
(30.0%) or to both of them (10.0%). It still has been shown
anastomosis among different collectors.
