Q
A

Pneumonia crouposa

  • more severe form
  • damage of vessels are so severe that fibrinogen are able to come out of circulation and polymorise to fibrin
  • lung tissue becomes firm, like liver tissue

Normal kidney structures with glomerulus and tubules
35
oxalate nephrosis -nothing else will look like this--> easy to recognize - its a result of ethylene glycol poisoning (antifreeze)
36
oxalate nephrosis oxalate crystals
37
oxalate nephrosis oxalate crystals
