Question is why water is important?                                        

have you ever think about this question?                               

                                

water is known as life line of living beings,plant animals or insects require specific amount of water in their body to carry out essential functions for living.

• Life can not be sustained without water
• human and animal may live for more days without food but die in fewer days if deprived of water.

• Function of water as a major component in body metabolism.
• As a major factor in body temperature regulation.
• All the biochemical reactions that take place in an animal require water.
  

  
• Act as solvent for a wide variety of compounds.  Due to this solvent action, it helps in the transport of dissolved nutrients in the system and helps in the excretion of end products of metabolism.  Many compounds readily ionize in water.  Salts within the body dissociate into ions, which have specific action in body tissues.  It serves as a carrier of digestive juices, enzymes and hormones.
• It is a medium for hydrolysis of nutrients in the system.
• It provides cell rigidity, fluidity and elasticity.
• It serves as lubrication fluid in the synovial cavities.
• It serves as a medium for transportation of semisolid digest in the gastrointestinal (GI) tract; medium for various solutions like blood, tissue fluids and cell secretions and excretory fluids such as urine and sweat.

• Water consumption is related to

• Heat production
• Energy consumption
• Body surface area in non-stressing situations.

It is estimated that water consumption may increase by 12% during heat stress.

• 
  
• Young one generally require more water than adult per unit of body weight.

Sources of water:-

• Drinking water
• Water contained in feed or bound water
• Metabolic water or oxidation water: Water that is provided to the animal by metabolic processes is called as metabolic water or oxidation water. Oxidation of carbohydrates yield 60% of its weight as water, protein yields 42% and fats yield 100%. Metabolic water plays important role under certain physiological conditions of the animal. In hibernating animals it is the only source of water. To a certain extent metabolic water is a source of water for animals living in deserts.
