- protein
- repair and growth to body
- fish, meat and eggs
- repair and growth to body

- fibre

- bran and cereal
- cleans our digestive system
- water
- needed for chemical reactions in body
- water or any juice
- needed for chemical reactions in body
- carbohydrates
- the digestive system
- mouth
- produces saliva
- teeth
- grinds food into smaller pieces
- saliva
- makes food most so easier to digest also adds enzymes
- oesophogus
- transports food from mouth to stomach
- stomach
- holds hydrochlolric acid which breaks food even smaller
- small intestine
- takes nutrients from chyme (pre- faeces) into blood
- enzymes
- help move food though the various zones of the system
- pancreas
- makes enzymes and adds to chyme
- large intestine
- takes the water out of chyme and adds to blood this then cause the chyme to become faeces
- rectum
- where faeces is held
- anus
- where faeces comes out of the system
- mouth
- Heat transfer
- by conduction
- metal is a good conductor
- conduction can only take place in solids
- the particles in conduction vibrate which causes the vibration to spread
- by convection
- convection can happen in liquids and gases
- convection is a current that heats then cools
- convection is in every day life hot air balloon and radiators
- by radiation
- this can happen when there are no particles.
- this moves in waves and in all directions
- radiation adsorbs and reflects the waves so black things absorb heat and waves and white reflects heat and waves
- by conduction
- food groups
