  17. Where is bile made?
    In the liver
  18. Where is bile stored?
    In the gall bladder
  19. What does bile do?
    It emulsifies fats (breaks them down into smaller droplets)
  20. The _________ creates digestive juices containing enzymes which is passed into the small intestine?
  21. Why is the small intestine good at its job?
    As it has a large surface area and a good blood supply

  24. Fatty acids and glycerol diffuse into _____ in the villi?
    the lacteal
  25. Why can soluble food diffuse across the villi efficiently?
    As it is only one cell thick
  26. Where is water reabsorbed?
    In the large intestine
  27. Describe peristalsis
