2.75 Urine

  • Urine contains salts, water and urea.
  •  Water and salt particularly affects the composition of the tissue fluid. This is called osmoregulation.
  • The removal of urea is part of the process of excretion of metabolic waste.
  • The composition of urine varies depends on the condition of each person, both externally and internally.
