Why Water is a essential nutrient for life?

In this unit, we learnt that water in spite of being ignored, is an essential nutrient required for life. Though the content of total body water varies from individual to individual, it plays a key role in the body. You would recall that these involve carrying several nutrients and waste products throughout the body, serves as the solvent for minerals, vitamins, amino acids, glucose and a multitude of other small molecules, and acts as lubricant and cushion around joints, aids in body's temperature regulation, selves as a shock absorber inside the eyes, spinal cord and in pregnancy, the amniotic sac surrounding the foetus in the womb and actively participates in many chemical reactions. , Then we saw that water is a constituent of every cell of the body intracellular fluid spaces between cells (interstitial space), and also within the blood (intravascular fluid). Water, is obtained from various sources such as beverages, solid foods and energy-yielding nutrients within the body. On the other hand, water is eliminated from the body through urine, skin, lungs and faeces. We, then, learnt about a variety of sensitive physiological control systems. Finally, we came to know that in order to be adequately hydrated, the average adult should consume about two litres of fluid per day, in the form of clean water and in addition consume non-caffeinated, non-alcoholic beverages, soups, milk, butter milk, and other beverages. The disturbances in fluid balance, is of two types: dehydration and oedema.
