Anatomical, Radiological, and Corrosion Casting of the Liver, Gallbladder, and Biliary Duct System of Local Breed Cattle (Bos ttaurus)

Abstract

Local breed cattle's liver, reddish-brown, occupies the right hypochondriac region with 35.2 ± 3.24 cm long and 5.5 ± 0.5 kg weight. Connected by left and right triangular ligaments; and falciform ligaments with the diaphragm, and hepatorenal ligament with the right kidney. While the coronary ligament encompassing the caudal vena cava divides into dorsal and ventral branches, enclosing the nuda region. The round ligament connects the umbilical fissure to the umbilicus. The lesser omentum on the liver's visceral surface connects the stomach and duodenum through hepatogastric and hepatoduodenal ligaments, respectively. The liver has, parietal and visceral surfaces; right, left, ventral, and dorsal borders; and left, right, caudate, and quadrate liver lobes that are not clearly separated, except for the caudate. The gallbladder has a dark green color and pear-shaped morphology, measures 16 ± 1.5 cm, and is located in a shallow cystic fossa.  Consisting of the neck, forms an inverted funnel shape, body, and fundus. The diameters were 2 ± 0.3, 6 ± 1.2, and 4 ± 1.3 cm, respectively. The biliary tract consists of extrahepatic and intrahepatic ducts. The extrahepatic ducts have a left duct of 3 ± 0.5 cm and a right duct of 2 ± 0.25 cm. Converging to form a common hepatic duct 8 ± 0.5 cm. The cystic duct is 3± 0. cm, joins with the common hepatic duct ventrally. The intrahepatic ducts consisted of primary, secondary, tertiary, interlobular, intralobular, and intercalated ducts. The left hepatic duct received 9 ± 1 of dorsal primary ducts and 8 ± 2 ventral primary ducts. The right hepatic duct receives 4 ± 1 dorsal ducts and 2 ± 1 ventral ducts.
