- CIRCULATORY SYSTEM
- starting at the aorta...
- O, arteries, goes to the capillaries in the body
- DO, veins, goes to the vena cava
- DO, pulmonary artery, to the lungs
- goes to capillaries in lungs
- O, pulmonary vein, goes to the heart.

- DIGESTIVE SYSTEM
- mouth-mixes w/ enzymes
- oesophagus- carries food from mouth to stomach
- liver - produces bile,, helps digest fats in small intestine
- stomach - adds acids and enzymes, mixed up (churning)
- gall bladder- stores bile
- pancreas - produces enzymes that are released into the small intestines
- small intestines - food digested by enzymes, food molecules are absorbed into blood
- large intestines - some water absorbed, undigested food forms faeces that pass out of the..
- anus.

- VILLI
- folded to create a larger surface area
- large capillary
network carries
absorbed molecules
rapidly away
- inside body tissues
- on top of each villi are
micro villi which increase
surface area more
- for diffusion of soluble products of digestion
- for diffusion of soluble products of digestion
- folded to create a larger surface area
- PREBIOTICS
- encourage beneficial bacteria to grow to protect from diarrhoea
- increasing evidence
- encourage beneficial bacteria to grow to protect from diarrhoea
- PROBIOTICS
- friendly bacteria
- lactobacillus
- claim to make you healthier
- friendly bacteria
- visking tubing as a model
- investigates digestion
- inside of tube is like a

- start - water around the tube
- end - glucose has diffused out of the bag into the water
- investigates digestion
