Digestive system vascular anatomy, 1866 illustration. In this abdominal dissection, the aorta (red) and vena cava (blue) blood vessels are shown at the point they diverge into the groin and legs. The organs seen here include the liver (upper left), the pancreas (yellow), spleen (top right), and kidneys. The stomach and most of the intestines have been removed. This page is plate 19 from the third volume of 'Atlas d'anatomie descriptive du corps humain' (1844-1866) by French anatomists Constantin Bonamy and Paul Broca. This work described the anatomy of the human body with over 250 hand-coloured lithographs. The illustrations were by Emile Beau, with the text by Bonamy and Broca. The three volumes were bound as four books in 1866 when the atlas was completed. This page is from the third book 'Digestion', a republication of the section on the digestive system that was first published in 1850.
