| Abstract | ||
| The study was carried out on (12) livers of adult healthy geese and duck of both sexes. They divided into two groups, the first group was subjected to gross feature regarding to shape, position, relationship in both birds by using cross dissection, while the second group used for radiographic study. The main purpose of this study is to convey more precise explanation of the gall bladder; the present study is conducted to give detailed information of the gall bladder and biliary duct. From the side of their topographic relation that may give a useful base for the hepatic segmentation. In these birds; the aim is to provide a correct base for avian anatomy, medicine gall bladder and biliary ducts. Also there are differences have seen in the shape andthe brunches of biliary ducts in both sexes of geese and ducks. Therefore the study shows that the cystecoenteric duct in geese is curved and short, but in ducks it is striated and long and it is also drainage in the major duodenal opening in both kinds of birds. In geese the results revealed that the gall bladder has a cylindrical shape and simply and it is attached to the live rand surrounding organs by connective tissue from seven areas. It is divided into three parts (neck, body and fundus). In ducks, the gall bladder has a bean shape and it is attached closely the liver and around organs by connective tissue from six areas, and divided into two parts (body and fundus). We can observe through the analysis of the cross and radiological photos, that the enternal hepatic ductules are divided into two parts (ventral and dorsal). Some parts of them are gathered to consist the (right and left hepatic ducts). Also these two ducts are gathered to shape (the common hepatoenteric duct) which is united with the (pancreatic duct) in geese, in order to drainage to the minor duodenal opening. While in the ducks, it drainages to the major duodenal opening with the cysticoenteric duct, and also the pancreatic duct drainages to the minor duodenal opening. Also there are differences in the other part of internal hepatic ductules in both kinds of birds and sexes. However the ductules are drainage directly in gall bladder in the females of geese, which are about (5-6) ductules, in the right lobe while in the left lobe is only one ductules. In the males of geese, the number of ductules is about (4-5) to the right lobe but in the left lobe is about (1-2). All these ductules in males of geese are drainage in main duct then they drainage in the gall bladder. The number of ductules is about (6-7) in the right lobe in the female sex of ducks. While in the male I about to (7-8). In the left lobe it is only one duct in both sexes. Therefore the ductules of both lobes are drainage in the main duct then to the gall bladder in both sexes. After all, the study proves that the bile material is movily from the liver to the intestine by two ducts while this case is not exist in mammalian. | ||
