The aim of this study was io supply of basic knowledges for the experimental research on rabbit, which was used widely as a laboratory animal. A total of 22 adult New Zealand Rabbus consisting of 15 males and 7 females were used in this study. Fifteen rabbits consisting of 10 mates and 5 females were given latex for making dissection and 3 males and 2 females rabbits were used lor the corrosion casts and also 2 males rabbits for the histological sections ol Ihe hepatic artery. Liver, hepatic artery, portal vein and biliary ducts were investigated macro-anatomically and subgrossly and the following results were found. In the rabbit, the liver was consist of six lobes and Ihe gall bladder was located between the quadrate lobe and the right hepatic lobe. Common bile duct which was opened at the beginning of the duodenum, was formed by joining of the hepatic ducts which are coming Irom ihe liver lobes. In the duodenum the common bile duct made mucosal bubble which called" papilla duodeni major". The celiac artery gave off the splenic artery which was the first branch of this artery, then it gave off the left gastric artery and the vessel continued as the hepatic artery. The hepatic artery gave off Ihe gastroduodenal artery and the right gastric artery respectively and arrived lo the liver inside the lesser omentum then the hepatic artery dispersed to the liver lobes. In the rabbit, portal vein was formed by the left ramus and right ramus of the liver and the first branch of the portal vein was the gastroduodenal vein. The left gastric vein and splenic vein were leaved, the portal vein as a common trunk cranial mesenteric vein, which was the largest branch of the portal vein, divided to Ihe two branches which were called the common jejunal vein and the ileocolical trunk. Finally, It was founded that the portal vein gave off the caudal pancreaticoduodenal vein and the caudal mesenteric vein.
