The Importance of Maintaining Adequate Levels of Water

Too Little Water

• Inadequate perfusion due to low blood volume
• A build up of waste products due to insufficent urine volume
• Increased solute concentrations affect cell function
• Inability to sweat and control body temperature
• Death

Too Much Water

• Oedema
• Increased blood volume and therefore pressure could damage the CVS
• A decrease in solute concentrations disrupt normal cell function
