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.

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. • 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.

necessary for cell energy and provides materials for cell 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.

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.
