Abdominal anatomy. 19th century artwork showing the anatomy of the abdomen from the rear. The liver (dark red) is at top right and the spleen at top left (purple). At top centre are one of the vertebra of the spine, the aorta (red), the body's main artery, and the vena cava (blue), the body's main vein. Parts of the large intestine are seen at right, left and bottom. This anatomical artwork is plate 7 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).
