| Food contains the energy that
powers the human body. Taste, sight and smell make it attractive, if
hunger was not enough. The teeth and jaws reduce it in size and then
it passes to the stomach. The stomach is the heart of the human
digestive system, as it is both a food mixer and acid and enzyme bath.
It squeezes the food into a semi-liquid called chime. From there, it
goes to the small intestine, where chemical digestion continues and
most nutrients are absorbed. The large intestine forms the leftovers
into brownish, semisolid masses, ready for disposal. The urinary
system handles the liquid waste. Our anatomical models show both the
digestive and urinary systems. Other models concentrate on the
primary organs, such as the kidneys, liver and gall bladder. |
