Blood vessels in the stomach wall, coloured scanning electron micrograph. The vessels supply mucus-secreting glands, which occupied the spaces in the network. The mucus protects the stomach wall from its own acid. This is a cast: the vessels were filled with a resin, which then set. The surrounding tissues were then eaten away chemically, leaving the cast of the vessels. Magnification: x170 when printed 10cm wide.
