C
hildren are fascinated by the workings of the digestive system.
Tey relish crunching a potato chip, delight in making “mustaches” with milk,
and giggle when their stomach “growls.” As adults, we know that a healthy diges-
tive system is essential to life, because it converts foods into the raw materials that build
and fuel our body’s cells. Specifically, the
digestive system
takes in food, breaks it down
into nutrient molecules, absorbs these molecules into the bloodstream, and then rids the
body of the indigestible remains.
