THREE LAYERS OF FOOD IN FROZEN STOMACH OF RAT

The human stomach, like the stomach of a rat, is relatively simple anatomically, and can be divided into sections with their own distinct functions. The illustration shows food eaten by a rat in three successive stages, the feed of each state stained with a different color for identification purposes. After the contents settled in three laters (identified by the numerals 1, 2, and 3), the stomach was frozen and removed for examination. Number 1 was the first and largest feeding; number 2 and number 3 were subsequent smaller feedings, each feeding making a nest cradling the next one.
