- - - - urine
        
        urine infection/renal function/loss of renal protein
      - cerebrospinal fluid
        
        produced in choroid plexus; flow through ventricles in brain and central canal of spinal cord to reach the space between brain/spinal cord and meninges
        
        normally= very few cells--> can be used to see brain disease
  - - - find out cause (aetiology) & development (pathogenesis) of disease
  - - - H&E (haematoxylin and eosin)--> stain cytoplasm pink and stain nucleus blue
      - gram (bacteria), Prussian Blue reaction (haemosiderin), Masons's trichrome (fibrous tissue)
  - - - tumour diagnosis/identify infectious agents
- - - - virus=food and mouth disease virus, seen as cutaneous vesicles in the nose of pig
      - bacteria= actinomyces bovis (osteomylitis--inflammation of bone)
      - parasitic disease= lungworm
  - - - yew poisoning in cattle-->cardio failure; antifreeze posioning,kidney failure
  - - - vitamin E (selenium) deficiency--> free radical damage to muscle (esp heart)-->pale degenerate muscle (white muscle disease)
- - - - toxic damage to the lung from a metabolite in fresh grass; seen as bubbles in the lung
