Produces enzymes

12

Small intestine

Causes chemical changes
Absorbs nutrients in the blood vessels

13

Absorption

Movement of digested food from the small intestine into the blood

14

Villi

Tiny hair like fingers, digested food through villi into blood vessel

15

Glucose and amino acids

Goes into blood

16

Fatty acids and glycerol

Lymph system then into blood

17

Blood vessels

Puts digested into cells
