Notes: Digestion: where the body breaks down food into useable
energy
1.
Start chewing, mouth creates saliva which begins to break down
food.
2. The food moves through the esophagus (which is a muscle) that
moves the food to the stomach.
3. Food moves into the stomach which is like a mixer. It churns and
mixes the food while breaking it down and killing harmful bacteria.
4. Food moves into the small intestine, here the body absorbs all the
vitamins, nutrients, and proteins, fats, and carbohydrates for your
body.
5. The liver and pancreas release chemicals to help breakdown the
food in the intestine. The useable nutrients are absorbed into the
bloodstream.
6. The large intestine takes the undigested food. Here water and salt
are absorbed. The leftover undigested food, harmful bacteria, and
dead cells remain. The body moves the feces towards the anus
for exit.
