  • the human digestive system
    • an organ system in which organs work together to digest and absorb food
    • liver
      • bile is produced
      • bile neutralises stomach acid and emulsifies fats
    • pancreas
      • produces protease, amylase and lipase
        • then released into the small intestine
    • gall bladder
      • bile is stored here before being released into the small intestine
    • large intestine
      • where excess water is absorbed from food
    • rectum
      • where the faeces is stored before being excreted through the anus
    • small intestine
      • produces protease, amylase and lipase enzymes to complete digestion
        • where digested food is absorbed out of the digestive system into the blood
    • gullet
      • the oesophagus
    • salivary glands
