Digestion Flow Chart

Complete the Digestion flow chart using the following organs of digestion, the various

processes that occur in them, the nutrients that are digested, and state whether it is

chemical or mechanical digestion.

Organs:

Mouth

liver

Stomach

pancreas

small intestine

large intestine

esophagus

rectum

gall bladder

salivary glands

Processes:

1. Amylase (enzyme) breaks down starch into simpler sugar

2. Produces bile

3. Mucus allows food to slide down with peristalsis

4. Stores bile

5. HCL and pepsin start to break down protein into amino acids

6. Most digestion occurs here

7. Most absorption of nutrients occurs here

8. Absorption of water, vitamins and minerals

9. Produces enzymes for the digestion of fat, carbohydrates and protein

10. Waste material is compressed into solid form

11. Expulsion of solid waste occurs here.

12. Bile breaks apart fat into fatty acids here.

13. Enzymes digest fat, protein and carbohydrates here.

14. Villi absorb nutrient molecules into bloodstream for cells to use

15. Muscles churn to break apart nutrients and create a soupy mixture of mostly undigested

nutrients called chyme.

16. Teeth cut, grind and tear food.

Mechanical and Chemical Digestion

Write CD or MD next to the organ’s process to show where chemical and mechanical digestion

occurs.

Identify the Nutrients

Use a yellow highlighter to highlight nutrients that are ABSORBED into the bloodstream.

Use a blue highlighter to highlight a nutrient that is DIGESTED in an organ.
