Liver. 19th century artwork of a section through the abdomen at the level of the twelfth thoracic vertebra (white, lower centre). The liver fills almost all of the abdominal cavity. The aorta (red), the body's main artery, the vena cava (blue), the body's main vein, and the oesphagus (gullet, pink) are above the vertebra. This anatomical artwork is plate 35 from volume 5 (1839) of 'Traite complet de l'anatomie de l'homme' (1831-1854). This 8-volume anatomy atlas was produced by the French physician and anatomist Jean-Baptiste Marc Bourgery (1797-1849). The illustrations were by Nicolas-Henri Jacob (1781-1871).
