AB All  tissues  in  the  body  are  composed  of  parenchymal  cells,  which  are  specialized  to  perform  the  functions  of  that  particular  tissue,  and  interstitial  connective  tissue  elements,  which  act  as  the  supporting  framework  of  the  tissue  (Figure  I-1).  Human  disease  results  from  the  action  of  various  injurious  agents  on  tissues.  Injurious  agents  may  act  on  parenchymal  cells  or  interstitial  connective  tissue,  causing  biochemical  or  structural  damage.  Biochemical  damage  may  result  in  abnormal  function  and  disease  without  producing  any  structural  alteration  in  tissue.  Structural  damage  may  sometimes  be  recognized  only  by  microscopic  examination  of  the  tissue.  In  parenchymal  cells,  it  results  either  in  reversible  changes  short  of  cell  death  (cell  degeneration)  or  in  irreversible  cell  death  (necrosis).  These  are  discussed  in  Chapter  1:  Cell  Degeneration  &  Necrosis.  Interstitial  tissue  damage  results  in  interstitial  abnormalities  (Chapter  2:  Abnormalities  of  Interstitial  Tissues).  Parenchymal  cell  damage  may  result  from  interstitial  abnormalities  and  vice  versa.
