Conformation and anatomical relations of the liver of llama (Lama glama)

Morphological studies of the liver of the llama are structural supportive to the clinical practice, surgery and specific diagnostic techniques. The aims of this study were first to determine the location of the organ and the direction of its major axis to project it to the abdominal wall, identifying visible and palpable bony references. Secondly, to characterize and determine anatomical relations of the surfaces, borders and angles of the llama liver, as well as, of its lobulation. Twenty adult llamas of both sexes and two foetuses of 6.5- and 7-month-old were used. Llama liver is a post-diaphragmatic organ located in the cranial abdominal region, in the right hypochondrium, in relationship with the last six ribs. Dorsally, it can exceeds the last (twelfth) rib. Its major axis presents a cranio-ventral bent. Its shape is irregularly triangular. It presents two surfaces (parietal and visceral), three borders (cranial, caudal and ventral) and three angles (dorsal, cranial and caudal).
