Guided Notes

Key concepts students will learn:

  • The digestive system is comprised of ten organs covering nine meters and transforms food into nutrients and energy.

  • The gastrointestinal tract transports food, while the pancreas, gallbladder, and liver break down food using special juices.

  • After about three hours in the stomach, the bolus becomes a frothy liquid called chyme, which moves into the small intestine where fats are dissolved by bile.
