The liver and digestion
- Emulsifieslipids, breaking them up physically into tiny droplets. Tiny droplets have a much larger surface area, over which lipases can work, than larger pieces, or drops of lipid.
- Contains sodium hydrogencarbonate, which is an alkali. It neutralises stomach acid and produces the optimum pH for pancreatic enzymes.
- Is produced in the liver, but stored and concentrated in the gall bladder.
