Complete the flowchart by filling in the:
a. Circles with organs the food will pass through (beginning with the mouth)
b. Squares with the mechanical action that occurs
c. Triangles with the digestive juices produced to break down food



Consider:

Where do the nutrients go when they leave the digestive system? How do they get there?

Does the digestion process change depending upon what I eat?

Compare the calories from carbohydrates, proteins, and fats. Which will give me more potential energy? Which source is easiest to access? What happens to that potential energy if it is not used?

If I starve my body, how do I continue to get energy? What effect does this have on the body?

Research a nutritional deficiency and its effect on the body. What foods contain this nutrient?

How many twinkies would it take to get 100% of my daily need for calcium, iron, Vitamin A and Vitamin C? And what percent of my daily fat intake is this? How many excess calories is this? How many pounds would I gain in a week if I continued to eat this way?

Do the same calculations with your favorite junk food!
