Classwork
• 1. What does the digestive system do?
• 2. Why is it important? Support your answer.
• 3. Predict what would happen if you could not
digest your food.
• 4. Describe what other body systems the
digestive system works with.
Classwork
• 1. What does the digestive system do?
• Breaks down the food into molecules that can be
used by the cells, molecules cell by blood,
eliminates waste products
• 2. Why is it important? Support your answer.
• 3. Predict what would happen if you could not
digest your food.
• 4. Describe what other body systems the digestive
system works with.

• Breaks down the food into molecules that can be
used by the cells, molecules cell by blood,
eliminates waste products
• 2. Why is it important? Support your answer.
• The digestive system is important because the
nutrients are necessary for cell energy and provides
materials for cell growth and repair.
• 3. Predict what would happen if you could not
digest your food.
• 4. Describe what other body systems the digestive
system works with.

• The digestive system is important because the nutrients are

growth and repair.
• 3. Predict what would happen if you could not digest your
food.
• The digested food provides energy to work and materials to
work with in order to replace/repair old cells and to make
new ones.
• 4. Describe what other body systems the digestive system
works with.

• 4. Describe what other body systems the digestive system works
with. The digestive system works with the muscles to move the
food through the system, the nerves/brain tells the muscles when
and where to move, the bloodstream picks up the nutrients in the
small intestine to distribute all over the body.
