THE DIGESTION PROCESS
2
THE DIGESTION PROCESS
  • The Digestive System turns FOOD into the fuel we
    need for energy and materials we need to grow and
    repair cells.

3
Digestion in the mouth
  • We chew our food with our teeth, mix it with
    saliva with our tongue and swallow (Food bolus).

4
Digestion in the stomach
  • The esophagus has muscular walls to push the food
    bolus along to the stomach.

5
Digestion in the stomach
  • The stomach mixes the food bolus, liquids and
    digestive juices for about two hours (chyme).

Digestion in the small intestine
  • Digestive juices in the small intestine
    (including bile from liver and pancreatic juices
    from pancreas) break down our food (chyle).

Digestion in the small intestine
  • Food is pushed through the seven meters of small
    intestine. Nutrients are absorbed into the blood
    and circulate throughout the body.
