Physical change/breakdown
Chemical change/breakdown
2
Physical change
Teeth grinds foods
Stomach churns food into chyme
3
Chemical changes
Digestive enzymes breakdown macronutrients
4
Protein
Amino acids
5
Fat

Cut grinds foods
Salivary amalayse carbs ---> maltose

Turns food into chyme produces enzyme, acid in stomach helps pepsin breaks down protein
10

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
18
Large intestine
Faeces is pushed out of rectum by peristalsis
