    an excess of blood within blood within blood vessels in a part of the body
  23. hyperplasia
    an enlargement of a tissue or organ resulting from an increase in the number of normal cells
  24. hypertrophy
    an enlargement of a tissue or organ resulting from an increase in the size of its individual cells
