Answer:
Food is our fuel, and its nutrients give ourbodies' cells the energy and substances theyneed to work. But before food can do that, itmust be digested into small pieces the bodycan absorb and use.
The first step in the digestive processhappens before we even taste food. Just bysmelling that homemade apple pie orthinking about how delicious that ripetomato is going to be, you start salivating -and the digestive process begins inpreparation for that first bite.
Almost all animals have a tube-type digestivesystem in which food:
enters the mouth
passes through a long tube
exits the body as feces (poop) throughthe anus
Along the way, food is broken down into tinymolecules so that the body can absorbnutrients it needs:
Protein must be broken down intoamino acids.
Starches break down into simplesugars.
Fats break down into into fatty acidsand glycerol.
