Question Answer Link
What are the problems if body water levels drop too low?
  • Inadequate perfusion due to low blood volume
  • A build up of waste products due to insufficient urine volume
  • Increased solute concentrations affect cell function
  • Inability to sweat and control body temperature
  • Death
 Link
What are the problems if body water levels get too great?
  • Oedema
  • Increased blood volume and therefore pressure could damage the CVS
  • A decrease in solute concentrations disrupt normal cell function
