Stomach arteries. Historical illustration of the arteries of the stomach. The arteries are coloured red, showing that they supply oxygenated blood. At top, the stomach (upper right, receiving arteries) is surrounded by other abdominal organs. From upper left: the liver (large, grey), the gall bladder (small, pear-shaped), the pancreas (white, horizontal) and the spleen (far right). In the bottom diagram the end of the oesophagus (lower left) leads into the stomach. The pylorus (lower right) channels food onwards to the duodenum, the start of the small intestine. Colour lithograph by Fairland from The Vessels of the Human Body, 1837. Based on drawings by J. Swandale.
