The distribution of the hepatic arteries within the liver in 30 Korean native cattle were observed. Vinylite solution was injected into the hepatic arteries of 10 livers for cast preparation. The angiography was prepared in 20 livers by injected 30% barium sulfate solution into the hepatic arteries and then radiographed on X-ray apparatus. The results were summarized as follow ; 1. The hepatic arteries were divided into the Ramus (R.) sinister, R. dexter and R. intermedius. The intrahepatic arteries were derived from the R. sinister and R. dexter. The R. intermedius divided into the Arteria(A.) gastrica dextra, A. gastroduodenalis and A. cystica. 2. The right branch (ramus dexter) of the hepatic artery supplies the right lobe and caudate process. It consisted of the A. dorsalis lobi dextri, A. ventralis lobi dextri and A. lobi caudati. They formed one common trunk with three arteries(6 cases, 20%), and two arteries formed common trunk with the A. ventralis lobi dextri and A. lobi caudati (16 cases, 52.8%), or with A. dorsalis lobi dextri and A. lobi caudati (5 cases, 16.5%). The three arteries arose from the A. hepatia independently(3 cases, 10%). 3. The left branch (ramus sinister), larger than the right and often double (6 cases, 20%), supplies the caudate, quadrate and left lobes, and often gives origin to the A. gastrica dextra. 4. The branches of hepatic artery in the left lobe were derived from A. dorsalis lobi sinistri, A. ventralis lobi sinistri and A. intermedius lobi sinistri. The A. intermedius lobi sinistri were absent in some cases (3 cases, 10%). They almostly originated a single branch and often two branches. 5. The A. cystica arose from the R. intermedius(27 cases, 90%) and A. hepaica(3 cases, 10%). 6. The Rami processus papillarum arose from dorsal border of the Pars transversa of the left branch(19 cases, 62.7%), the left branch and right branch (9 cases, 30%) or A. hepatica(2 cases, 6.6%). 7. The A. lobi quadrata arose from either the Pars transversa of left branch (12 cases, 40%) or A. hepatica(4 cases, 13.2%). It also arose from both Pars transversa of left branch and A. ventralis lobi sinistri (3 cases, 10%). 8. The anastomosis on the branches of A. hepatica was observed in intrahepatic and cystic arteries. The left and right branches ramified several secondary radiating branches within the liver. 9. The hepatic arteries formed a very short common trunk of the right branch ($18.75{\pm}11.89$ : 2.20~44.8mm) and a long Pars transversa of the left branch($72.85{\pm}20.04$ : 28.2~104.1mm). 10. The ramified angles at the A. dorsalis lobi dextri, A. ventralis lobi dextri, A. lobi sinistri, A. ventralis lobi sinistri, A. lobi quadrata, A. cystica and Rami processus papillarum were 50-80, 270-300, 340-20, 120-160, 160-290, 200-230, 250~290, 230~280 and 80~120 degrees, respectively.
