It is best that the fluid surrounding the cells remains fairly constant. If volume is varied dramatically then it has major knock on effects on the blood pressure and perfusion of the organs and tissue.

==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 insufficient 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

Water intake during lactation increases significantly even over and above the requirement for milk. To produce 31l of milk and cow needs to take in an extra 57l of water. This is thought to be because of an increased loss from the airways, skin and faeces.
