Se observó la estructura macro y microscópica del hígado de 6 llamas adultas (Lama glama), 4 machos y 2 hembras. El hígado se ubica en la región abdominal craneal, a la derecha del plano mediano. Carece de vesícula biliar y el conducto hepático se une al conducto pancreático mayor, a unos 3 cm del duodeno, formando el conducto hepato-pancreático, el cual desemboca mediante el trayecto intramural en la segunda curva de la ese sigmoídea del duodeno. En los lobulillos hepáticos, el tejido conectivo de soporte es escaso, se halla limitado al espacio porta. Los estudios morfológicos brindan un soporte estructural para la realización de técnicas de diagnóstico específicas de este órgano, como por ejemplo, la biopsia hepática
The objetive of this study was the description of the macroscopic characteristics of the liver: position, anatomic relationships, peritoneal folds, lobes, irrigation, innervation, lymphatic drainage and biliary tree.The histologic description was carried out under the classic morphologic organization model (classic hepatic lobule). The macroscopic and microscopic structure of the liver in 6 adult llamas (4 males and 2 females) was observed. The liver was situated in the cranial abdominal region, to the right of the medial plane.The gall bladder was abscent in llamas.The bile duct was joined to the pancreatic duct at 3 cm from the duodenum forming the hepato-pancreatic duct, which empties by means of the intramural course in the second curvature of the sigmoid flexure of the duodenum. The hepatic lobules was limited by connective tissue near the portal area. Morphological studies offer a structural support to the specific diagnostic techniques of this organ, for example, liver biopsy
