  The  act  or  process,  by  which  living  tissues  or  cells  take  up 
  and  convert  into  their  own  proper  substance  the  nutritive 
  material  brought  to  them  by  the  blood,  or  by  which  they 
  transform  their  cell  protoplasm  into  simpler  substances, 
  which  are  fitted  either  for  excretion  or  for  some  special 
  purpose,  as  in  the  manufacture  of  the  digestive  ferments.
